Question
The standard Gibbs free energy of formation of NH3 is -16.5 kJ mol-¹ at 298 K. What is the reaction Gibbs free 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?
