Question

Which of the following is obtained by catalytic oxidation of ammonia?

पर्याय

• N₂O

• NO

• HNO₂

• NO₂

Answer 1

NO

Explanation:

Nitric oxide (NO) is obtained by catalytic oxidation of ammonia. The catalytic oxidation of ammonia uses a metal catalyst such as platinum, copper or nickel. This metal catalyst is heated, so that ammonia can reduce it, oxygen added to the system can then oxidise the ammonia, forming nitric oxide.
