What catalyst is used for oxidation of ammonia to produce nitric acid?

1.	What catalyst is used for oxidation of ammonia to produce nitric acid?(a) Palladium hydride(b) Sodium amalgam(c) Platinum-Rhodium gauze(d) Vanadium (V) oxideI have been asked this question in homework.The origin of the question is P-Block in section P-Block Elements of Chemistry – Class 12
Answer» Correct option is (c) Platinum-Rhodium gauze To elaborate: AMMONIA is oxidized to nitrogen (II) OXIDE in the PRESENCE of Pt/Rh gauze catalyst at a temperature of 500 K and a pressure of 9 bars. The NITROUS oxide is then converted to nitrogen dioxide which is further reacted with water to produce nitric acid. The NO FORMED is recycled.
