Question

How is ammonia manufactured industrially?

Answer 1

Haber's process is used for manufacturing ammonia.

$N_2\left(g\right)+3_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)$ ${\Delta }_f{H}^o=-46.1kJ/mol$

Optimum conditions (to obtain maximum yield of ammonia) are around $200$ atm pressure, $700$ K temperature and a catalyst containing iron oxide with small amounts of $K_{2}O$ and $A{l}_2{O}_3$. The reaction is reversible exothermic reaction and optimum conditions mentioned above are in accordance with Le Chatelier's principle.
