Question:
Mention the conditions required to maximise the yield of ammonia.
Solution:
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
