  1. Question 1

    Q1. In the industrial Ostwald process for manufacturing Nitric acid, which catalyst is employed during the step-wise oxidation of Ammonia to Nitric oxide?

    • A) Iron with Molybdenum promoter
    • B) Vanadium pentoxide
    • C) Platinum-Rhodium gauge
    • D) Nickel catalyst

    Answer: Platinum-Rhodium gauge

    Explanation: The Ostwald process uses Platinum-Rhodium catalyst to oxidize ammonia; Iron is tempting because it is used in the Haber process instead.
