For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction N2 (g) + 3H2(g) -------> 2NH3(g) the standard change in Gibbs free energy is ΔG° = -72.6 kJ/mol. What is ΔG for this reaction at 298 K when the partial pressures are PN2 = 0.200 atm PH2 = 0.350 atm PNH3 = 0.850
