Question

Write the equations involved in the manufacture of nitric acid by Ostwald's process by maintaining reaction conditions.

Answer 1

The equations involved in the manufacture of nitric acid by Ostwald's process are given below.

$4N{H}_3\left(g\right)+5O_2\left(g\right)\underset{\text{500K. 9bar}}{\overset{\text{Pt/Rh gauge catalyst}}{\to }}4NO\left(g\right)+6H_{2}O\left(g\right)$

$2NO\left(g\right)+O_2\left(g\right)\rightleftharpoons 2N{O}_2\left(g\right)$

$3N{O}_2\left(g\right)+H_{2}O\left(g\right)\to 2HN{O}_3\left(l\right)+NO\left(g\right)$.
