Question
Ammonia is manufactured by Haber Process.
State whether the formation of ammonia is promoted by the use of high pressure or low pressure?
Solution
\[\ce{N2 + 3H2 <=>[(Fe + Mo) at 450^\circ C to 500^\circ C][(200-900 atms)] 2NH3 + 22400 cals}\]
As volume of products is less than reactants
High pressure favours the forward reaction, i.e., the formation of ammonia.
