Question

Which catalyst is used in oxidizing \( NH_3 \) in Ostwald's process?

• A. Pt
• B. FeO
• C. \( V_2O_5 \)
• D. Molybdenum

Hint:

Vanadium pentoxide (\( V_2O_5 \)) is commonly used as a catalyst in oxidation reactions like the Ostwald process for the production of nitric acid.

Answer 1

The Correct Option is C

In the Ostwald process for nitric acid production, \( V_2O_5 \) (vanadium pentoxide) acts as a catalyst, oxidizing ammonia (\( NH_3 \)) to nitrogen dioxide (\( NO_2 \)). While platinum is also employed, \( V_2O_5 \) is the primary catalyst.
