For one of the questions on the midterm, was it correct to assume that the Gibbs Free Energy of H2 is zero?

Hi, if I remember correctly, yes. In an isothermal reversible process for an ideal gas (which H2) is, then the G value will not change, so delta G does indeed equal zero.

Elements in their standard states (H2, O2, etc.) have standard Gibbs free energy changes of zero because there is no change involved.
