What equations do you need to solve entropy problems

Posted: **Sat Feb 10, 2018 9:21 pm**

all variations of delta S = nRln(V2/V1), S = kBlnW, the gibb's free energy equation, delta S = qrev/T

these are just some I could think of right now, but there's probably more

The equations sheet that we received for the first test has all the entropy formulas you would need to solve any problem given; in addition to those listed above, there's the nCln(T2/T1), and the formula for standard entropy of formation.

Also know how to calculate residual entropy using the arrangement of molecules (W). As well as being able to identity when to use total entropy based on the pathways in the problem.
