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

The Correct Option is C
Solution and Explanation
In the Ostwald process for producing nitric acid, \( V_2O_5 \) (vanadium pentoxide) is used as a catalyst to oxidize ammonia (\( NH_3 \)) to nitrogen dioxide (\( NO_2 \)). Platinum is also used in some versions of the process, but \( V_2O_5 \) is the most common catalyst.
