Gibbs free energy heat capacity
http://micro.stanford.edu/~caiwei/me334/Chap9_NPT_Grand_Canonical_Ensemble_v04.pdf WebWe make use of the relationship between C p and H and C p and S. (22.7.1) ( ∂ G / T ∂ T) P = − H T 2 + C P T − C P T (22.7.2) = − H T 2. We said before that S is a first order derivative of G. As you can see from this derivation the enthalpy H is also a first order derivative, albeit not of G itself, but of G / T. ( ∂ Δ G / T ∂ T ...
