The standard heat of reaction H for gas-phase reactions is independent of the choice of standard-state pressure

Question:

The standard heat of reaction ΔH° for gas-phase reactions is independent of the choice of standard-state pressure P°. (Why?) However, the numerical value of ΔG° for such reactions does depend on P°. Two choices of P° are conventional: 1 bar (the basis adopted in this text), and 1.01325 bar. Show how to convert ΔG° for gas-phase reactions from values based on P° = 1 bar to those based on P° = 1.01325 bar.
