Question

Name the catalyst in the given case and write the chemical equation for:

Action of ammonia gas with oxygen

Answer 1

• Catalyst used is Platinum.
• Catalytic oxidation of ammonia is an exothermic reaction
• It is known as Ostwald's process which is done for manufacturing of nitric acid.
• $\underset{\mathrm{Ammonia}}{\underset{}{4{\mathrm{NH}}_3}}+\underset{\mathrm{Oxygen}}{\underset{}{5{\mathrm{O}}_2}}\underset{\mathrm{Pt}}{\overset{800°\mathrm{C}}{\to }}\underset{\mathrm{Nitric}\mathrm{oxide}}{\underset{}{\mathrm{NO}}}+{\mathrm{H}}_2\mathrm{O}$
