Solution

Manufacture of Ammonia $({NH}_{3})$ by Haber's Process:
In this process, a mixture of pure dry nitrogen $(N_{2})$ (obtained by fractional distillation of air) and hydrogen gas $(H_{2})$ in the ratio of $1 : 3$ by volume is compressed to 200-500 atmospheric pressure.
The compressed gases are passed over heated catalyst of iron at a temperature of $450 ° C$ to $500 ° C$ .
$N_{2} ↑ + 3 H_{2} ↑ \overset{Fe 500 ° C, 250 atm}{⇌} 2 {NH}_{3} ↑ + 22, 400 cal$
Reducing Action of Ammonia:
Ammonia is a strong reducing agent. It reduces metallic oxides and chlorine.
Ammonia reduces copper(II) oxide $(CuO)$ into metallic copper.
$3 CuO (s) + 2 {NH}_{3} (g) ⟶ 3 Cu (s) + 3 H_{2} O (l) + N_{2} (g) ↑$
The process is Haber's process.
The reactants must be taken in the ratio $1 : 3$ .
Iron is used as catalyst.
$N_{2} (g) ↑ + 3 H_{2} (g) ↑ \overset{Fe 500 ° C, 250 atm}{⇌} 2 {NH}_{3} (g) ↑ + 22, 400 cal$
$3 CuO (s) + 2 {NH}_{3} (g) ⟶ 3 Cu (s) + 3 H_{2} O (l) + N_{2} (g) ↑$
