Haber’s Process:
N2(g) + 3H2(g) \(\rightleftharpoons\) 2NH3(g)
Low temperature favours the exothermic reection because it releases energy. So the forward reaction is forward and the yield of ammonia will increase.
High pressure favours the reaction that decreaces the number of gas molecules so the forward reaction is favoured. The equilibrium will shift to the right and the yield of ammonia will increase.
