The standard Gibbs energy of formation of NH3(g) is −16.5 kJ mol−1 at 298 K. What is the corresponding reaction Gibbs energy when the partial pressures of the N2, H2, and NH3 (treated as perfect gases) are 3.0 bar, 1.0 bar, and 4.0 bar, respectively? What is the spontaneous direction of the reaction in this case?
