How ammonia is manufactured by Haber's process ?

Text Solution

Verified by Experts

Ammonia is manufactured by Haber's process by the direct combination of nitrogen and hydrogen.
`N_(2)(g)+3H_(2)(g)rarr2NH_(3)(g)`
According to Le- chatelier 's principle yield of ammonia is increased by
(i) High pressure of 200 atm.
(ii) Optimum temperature of 700 atm.
Use of catalyst like iron oxide with `K_(2)O and Al_(2)O_(3)`
