Question

Ammonia can be collected by liquefaction after preparation byv Haber's process.​

Answer 1

Answer:

On an industrial scale, ammonia is prepared by Haber’s process. The constituents of ammonia N

2

and H

combine in a ratio of 1:3.

N

+3H

⇌2NH

The reaction proceeds in the forward direction with a remarkable decrease in volume and thus the reaction is exothermic. In accordance with Le Chatelier’s principle, high pressure would favour the formation of ammonia. The optimum conditions for the production of ammonia are a pressure of approx 200atm, a temperature of approx 700K and the use of a catalyst such as iron oxide with small amounts of K
