Question

Mention the conditions required to maximise the yield of ammonia.

Answer 1

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
