With solid CuO and supply of heat, ammonia is oxidized to nitrogen gas and CuO is reduced to copper. This reaction is a exothermic reaction and it emits -904 kJ mol-1. Because the synthesis gas was essentially free of impurities, two axial-flow ammonia converters were used to attain a high ammonia conversion. So Why should chemical equations be balanced ? In some cases, additional reactants may be required. This is possible by using non-polluting methane pyrolysis or generating hydrogen by electrolysis of water (or steam) utilizing zero carbon electricity from renewable energy sources or nuclear power.
