Question

What is done to maximise the yield of ammonia in habers process?

Answer 1

Its an exothermic reaction.

We apply le chatelier principle

We get

1) high pressure

2)low temperature

3)catalyst Mo or Fe

Answer 2

Mention the conditions required to maximise the yield of ammonia. ... 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.
