Question

Condition required to maximise the yield of ammonia

Answer 1

2 High pressure on the reaction at equilibrium favours the shift of the equilibrium to the right because the forward reaction proceeds with a decrease in number of moles.Hence a pressure of about 200 atm will be optimal for the higher yield of ammonia.

Answer 2

Answer:

Ammonia is prepared using the Haber’s process.

The yield of ammonia can be maximized under the following conditions:-

(i) High pressure (∼ 200 atm)

(ii) A temperature of ∼700 K

(iii) Use of a catalyst such as iron oxide mixed with small amounts of K2O and Al2O3
