Question

describe the principal of manufacture of ammonia by Haber process.​

Answer 1

Answer:

The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. The catalyst is actually slightly more complicated than pure iron.

Answer 2

Explanation:

On an industrial scale, ammonia is prepared by Haber’s process. The constituents of ammonia N2

And H2 combine in a ratio of 1:3.

N2+3H2=2NH3

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 K2O and Al2O3 to increase the rate of attainment of equilibrium.
