A system contains H2, N2, and NH3 gases, each with a partial pressure of 0.50 bar. The temperature is held constant at 363.15 K. Calculate the Gibbs energy of reaction, AGp, for the formation of NH3(g) from N2(g) and H2(g) under these conditions and predict whether formation or consumption of NH3 is spontaneous. Ag for NH3(g): -16.45 kJ/mol; AG; for N2(g): 0 kJ/mol and AG; for H2(g): 0 kJ/mol
