Question

For the manufacture of Ammonia by Haber's process, write the equation and optimum conditions for maximum yield of ammonia.

Answer 1

$N{H}_3$ is manufactured by Haber’s process. In this process, pure nitrogen and hydrogen gases react in the ratio of $1:3$ by volume in ${400}^{0}C-{500}^{0}C$ temperature, $200-900$ atm pressure in presence of iron as catalyst and molybdenum as promoter.

$N_2+3H_2\underset{Fe/Mo}{\overset{400-{500}^{0}C}{\to }}2N{H}_3+Heat$
