### H2(g) --> H2(g) Entropy

Let's say we have H2(g) in some larger equation and we are attempting to determine the delta G for this rxn. Exluding the other products and reactants, I want to look at just changes in the values associated with H2.

Would the standard molar entropy be 0 (or 130.6 as I found in the Appendix)
Would delta G be zero or -130.6?

### Re: H2(g) --> H2(g) Entropy

The Molar Entropy of H2(g) is 130.68 Joules(K-1)(mol-1).

Gibbs Free Energy of Formation is 0 kilojoules per mol.
