### Homework Problem 4F.11

In problem 4F.11, why does the solution use the equation deltaS= nRln(T2/T1) instead of nCpln(T2/T1)?

I think it's because the problem does not state that it was at constant pressure and volume and pressure are inversely related so using C for constant pressure would not work in this case, where as S=nRln(v2/v1) is not pressure dependent.
