Vedclass · Answer

(B) The catalytic oxidation of ammonia is the first step in the Ostwald process for the manufacture of nitric acid.In this process,a mixture of ammonia and air is passed over a $Pt$ gauze catalyst at $800\,^{\circ}C$.The chemical reaction is:$4NH_3 + 5O_2 \xrightarrow{Pt, \,800\,^{\circ}C} 4NO + 6H_2O$Thus,the product formed is nitric oxide $(NO)$.

$A$ mixture of ammonia and air at about $800\,^{\circ}C$ in the presence of $Pt$ gauze forms:
