In the Ostwald process, the catalyst used for the oxidation of ammonia is: MCQ with Answer and Explanation

In the Ostwald process, the catalyst used for the oxidation of ammonia is:
A. Iron
B. Platinum
C. Nickel
D. Vanadium pentoxide
Answer: Option B
Solution (By JKSSB Mock Tests)
The Ostwald process is used to manufacture nitric acid. The first step involves the catalytic oxidation of ammonia (NH3) to nitric oxide (NO). This reaction is carried out at about 800°C using a platinum-rhodium gauge catalyst. Iron is used in the Haber process, and V2O5 in the Contact process.
