The Haber Process The Haber process is the industrial manufacture of Ammonia from Nitrogen and Hydrogen. The raw materials are: * air - for nitrogen, * methane and water - for hydrogen. The reaction is an exothermic reaction that is reversible and the equation is as follows: nitrogen + hydrogen ammonia ( + heat) N2(g) + 3H2(g) 2NH3(g) ( + heat) We obtain our raw material as follows: * Nitrogen is obtained from the 79% of air that is nitrogen by fractional distillation. * Hydrogen is obtained from methane (natural gas) or naphtha. The hydrocarbon is reacted with steam. Methane + steam carbon dioxide + hydrogen. CH4(g) + 2H2O(g) CO2(g) + 4H2(g) The industrial conditions that are preferred and you suggested are: 1) A temperature between 450 °C and 500 °C. Heat is treated in this reaction as a product (an exothermic reaction). If you remove heat from an exothermic reaction (cool it down), the equilibrium will shift to produce...
