### Calculating the change in entropy with constant pressure

When the question says the reaction is occuring at constant pressure, can we use C instead of C (p,m) in our equation (change in S = nC(p,m)ln(T2/T1)? Thanks!

For previous questions, C(p,m) = (5/2)R, so I assume you can just use this instead of C.
S = n(5/2)Rln(T2/T1)

I would stick with using C(p,m) in that deltaS equation, which as said by Joyce, is (5/2)R at constant pressure.
