The standard conditions are 298 K and partial pressure of 1 atm for all species for a gaseous reaction. The standard change in Gibbs free energy is ΔG° = –69.0 kJ/mol for the following reaction:
N2(g) + 3H2(g) ⇌ 2 NH3(g)
Calculate the ΔG for this reaction at 298 K when the partial pressures are: PN2 = 0.360 atm, PH2 = 0.520 atm, and PNH3 = 0.970 atm.
