BVT2 Physical Chemistry, catalog number CHEM 5310, is the two-competency-unit course covering thermodynamics, reaction kinetics, chemical equilibrium, electrochemistry and the nature of matter. The catalog lists it as a legacy code. Physical chemistry is where chemistry becomes quantitative, and the distinction that organizes the whole course is between whether a reaction can happen and whether it will happen quickly. Those are separate questions with separate machinery, and confusing them is the most common conceptual failure in the subject.
What CHEM 5310 is actually testing
Thermodynamics answers the first question. It tells you whether a process is favourable by accounting for energy change and for the dispersal of energy and matter, and it says nothing whatever about how long the process will take. A reaction can be thoroughly favourable and still proceed so slowly that nothing observable happens for years. Diamond converting to graphite is the textbook case, and it is worth carrying because it makes the separation between the two questions concrete.
Kinetics answers the second. Rate depends on how often particles collide with sufficient energy and correct orientation, which is why concentration, temperature, surface area and catalysts all change it. A catalyst lowers the energy barrier without altering the thermodynamics at all, which is exactly why the two frameworks have to be kept separate: a catalyst changes whether a reaction happens on a useful timescale and changes nothing about whether it is favourable.
Equilibrium sits between them. A reversible reaction reaches a state where forward and reverse rates are equal, so concentrations stop changing while both reactions continue. That dynamic character is what students most often lose, describing equilibrium as a reaction that stopped. Predicting how a system responds to disturbance follows directly from holding the dynamic picture, and it is a standard scored task.
Electrochemistry applies all three to reactions where electrons transfer between species, and it is the topic where physical chemistry becomes most visible in a classroom. A cell built from two metals in solution demonstrates favourability, rate and equilibrium simultaneously, which makes it unusually valuable for a future teacher to understand rather than merely to operate.
Planning study and written work from the rubric
Scoring detail lives inside your Course of Study rather than the public catalog. Read the aspects before allocating study time, because this course spans four quantitative areas in two competency units. Each aspect is scored on its own against a three-point scale, and a 2 in each aspect passes the task.
Where a performance assessment is used, structure by aspect and keep calculations inside the section they evidence, with the physical interpretation written beside the arithmetic.
The word budget, worked. Assume five scored aspects and roughly 1,400 words of written explanation alongside calculations and any data. Take 110 for framing and 90 for a close, leaving about 1,200 across five aspects, or 240 each. Then rebalance toward interpretation: an aspect asking what a computed quantity means for the system deserves 350, funded by keeping the arithmetic commentary near 160 since the working shows the method.
For an objective assessment, drill the separation between the two questions. For each situation, decide whether it is asking about favourability or about rate before touching any equation. That single habit resolves a large share of the confusion this subject generates.
A structure that fits a physical chemistry deliverable
Follow task directions on format wherever they specify one. Where the arrangement is yours, this order keeps the physical meaning ahead of the calculation.
| Section | What belongs in it | How it tends to be scored |
|---|---|---|
| System and question | The system, its boundary, and whether the question is about favourability or rate | Framing the question correctly determines everything after |
| Thermodynamic analysis | Energy change and dispersal, with signs and conventions stated | Sign conventions are a standard and avoidable loss |
| Kinetic analysis | Factors affecting rate and the mechanism where known | Scored for keeping rate reasoning separate from favourability |
| Equilibrium | The equilibrium expression, its value and what it indicates | Scored for describing the state as dynamic rather than stopped |
| Response to disturbance | How the system shifts when conditions change, and why | Explanation matters more than the direction of the shift |
| Electrochemistry | Half reactions, cell arrangement and direction of electron flow | Half reactions written separately are usually expected |
| Checks | Units, signs and physical plausibility | Sign errors survive algebra and only a check catches them |
Write half reactions separately in every electrochemistry problem. Splitting oxidation from reduction makes electron bookkeeping visible, prevents the most common balancing errors and shows the reasoning that a combined equation hides.
Evidence craft in physical chemistry
Quantitative chemistry claims are checkable in detail, and the details that get checked are usually signs, units and conditions.
- State sign conventions for energy transfer once and apply them consistently, since texts differ and an unstated convention makes a result ambiguous.
- Use absolute temperature in every thermodynamic and equilibrium calculation, and state units at each step.
- Keep favourability and rate separate in your writing. A catalyst changes one and not the other, and blurring them is the central conceptual error in the subject.
- Describe equilibrium as dynamic, with both reactions continuing at equal rates rather than as a reaction that stopped.
- Show half reactions and electron counts in electrochemistry rather than presenting a balanced overall equation alone.
- Cite data tables, texts and borrowed problems in APA where the rubric asks for citation, and keep quotation minimal since WGU scans submissions for authenticity.
The strongest work interprets every computed number physically. Saying that a large equilibrium constant means the products are strongly favoured at this temperature, and what that would look like in a flask, converts a calculation into chemistry and answers the aspect the arithmetic alone leaves open.
What separates Competent from work sent back
Assessment outcomes are Competent or Not Competent, with no letter grades and no ordinary grade point average. Performance assessment work can be revised and resubmitted without a grade penalty, so a return costs time inside a six-month flat-rate term.
Physical chemistry work that clears on the first read tends to have:
- The question identified as one about favourability or about rate before any calculation.
- Sign conventions declared and held throughout.
- Absolute temperature used everywhere it is required.
- Equilibrium described as a dynamic balance rather than a stopped reaction.
- Half reactions written separately with electrons balanced.
- Every computed value interpreted in terms of what the system would actually do.
Where a proctored objective assessment is part of this course in your plan, the boundary is fixed. Proctored exams are yours to sit. Support is preparation only: concept-separation drills, worked practice and an honest readiness verdict. We never ask for portal credentials.
Seven mistakes that cost time in BVT2
- Confusing favourable with fast. Thermodynamics and kinetics answer different questions, and merging them is the defining error of the subject.
- Equilibrium described as stopped. Both reactions continue at equal rates, and losing that makes every disturbance prediction guesswork.
- Celsius in a thermodynamic calculation. Absolute temperature is required, and a dimensional check will not catch the substitution.
- Undeclared sign conventions. A correct magnitude with an ambiguous sign convention cannot be scored as correct.
- Combined equations in electrochemistry. Half reactions make the electron bookkeeping visible, and skipping them hides the reasoning being assessed.
- Numbers without interpretation. A computed constant that is never connected to what the system does answers only half the aspect.
- Treating a catalyst as changing favourability. A catalyst lowers the barrier and speeds both directions equally, leaving the equilibrium position exactly where it was, and claiming otherwise is a standard conceptual return.
How support works on this course
Physical chemistry is returned for conceptual blending and for sign and unit failures far more than for algebra. Send the rubric from your Course of Study and the task directions if a written deliverable is involved. The work comes back with favourability and rate separated explicitly, conventions declared, absolute temperature enforced, equilibrium rewritten as a dynamic state, half reactions split out in electrochemistry, and every calculated value interpreted in terms of observable behaviour.
Two competency units in a flat-rate six-month term makes this a short course by unit count and a demanding one by content. Taking it after the inorganic course, rather than alongside it, usually works better, since bonding and reaction types are assumed here rather than developed. It is also the chemistry course with the most mathematics in it, so a week spent refreshing logarithms, exponentials and unit conversion before you begin tends to pay for itself several times over. Most of what students describe as physical chemistry difficulty turns out on inspection to be algebra under time pressure.
Questions students ask about BVT2
Is BVT2 the same course as CHEM 5310?
What is the difference between thermodynamics and kinetics?
Why is equilibrium called dynamic?
Thermodynamics and kinetics blurring together?
Send your rubric and any task directions. The two questions get separated explicitly, conventions get declared, and every computed value gets interpreted physically.

The assessments, one by one
The public catalog does not publish this course's PA/OA identity or task count. WGU Tutors publishes at most one PA manual per course and only from a WGU-controlled public rubric. Until that source exists, PA help begins from the student's real Course of Study and OA support remains preparation only.
