Consider the industrial preparation of sulfuric acid via the Contact process and nitric acid via Ost — Surface Chemistry Chemistry Question

💡 Solution & Explanation

In the Contact process for manufacturing $H_2SO_4$, the oxidation of $SO_2$ to $SO_3$ is catalyzed by Platinised asbestos or $V_2O_5$. In Ostwald's process for manufacturing $HNO_3$, the oxidation of $NH_3$ to $NO$ is catalyzed by Platinised asbestos at $573\text{ K}$.
