Haber Ammonia Process

Haber Process – the process by which ammonia is made from nitrogen and hydrogen. Nitrogen is obtained from air and hydrogen is obtained from methane. It follows the following equation:

N2 + 3 H2 <- -> 2 NH3 ΔH = -92 kJ/mol

Increasing the temperature will produce less ammonia because this will use up the added heat. Lowering the temperature will produce a greater yield of ammonia but will decrease the rate of the overall
Increasing pressure should move the equilibrium to the right to produce more ammonia. However this will increase the cost because of the thickness of the walls of the plant needed to contain the reaction and it means the temperature will increase and its
