Vedclass · Answer

(A) The industrial manufacture of nitric acid is carried out by the $Ostwald$ process. The steps are as follows:$1$. Catalytic oxidation of ammonia: $4 NH_{3} + 5 O_{2} \xrightarrow[800-900^{\circ} C]{Pt 	ext{ gauge}} 4 NO + 6 H_{2} O$$2$. Oxidation of nitric oxide to nitrogen dioxide: $2 NO + O_{2} \longrightarrow 2 NO_{2}$$3$. Absorption of nitrogen dioxide in water: $4 NO_{2} + 2 H_{2} O + O_{2} \longrightarrow 4 HNO_{3}$Thus, the intermediate compounds formed are nitric oxide $(NO)$ and nitrogen dioxide $(NO_{2})$.

Nitric acid can be obtained from ammonia via the formation of the intermediate compounds:
