One of the most extensively studied reactions of industrial chemistry is the synthesis of ammonia, for its successful operation helps to govern the efficiency of the entire economy. The standard Gibbs energy of formation of NH3(g) is -16.5 kJ mol-1, at 298 K. What is the reaction Gibbs energywhen the partial pressure 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?
