Vedclass · Answer

(D) The industrial production of nitric acid by the Ostwald process involves the catalytic oxidation of ammonia $(NH_3)$:$4NH_{3(g)} + 5O_{2(g)} \xrightarrow{Pt/Rh} 4NO_{(g)} + 6H_2O_{(g)}$Then,nitric oxide $(NO)$ is oxidized to nitrogen dioxide $(NO_2)$:$2NO_{(g)} + O_{2(g)} 	o 2NO_{2(g)}$Finally,nitrogen dioxide is absorbed in water to produce nitric acid $(HNO_3)$:$4NO_{2(g)} + 2H_2O_{(l)} + O_{2(g)} 	o 4HNO_{3(aq)}$Thus,$NH_3$ is the starting material.

Which of the following is used in the industrial production of nitric acid by the Ostwald process?
