Question

Name a catalyst and promoter used for preparing Nitrogen gas.

A. Catalyst: Platinum, Promoter: Iron
B. Catalyst: Nickel, Promoter: Rhodium
C. Catalyst: Iron, Promoter: Platinum
D. Catalyst: Rhodium, Promoter: Nickel

Answer 1

The correct catalyst and promoter used for preparing Nitrogen gas via the Haber Process are Iron and Platinum, respectively.

Step-by-step explanation:

The catalyst and promoter used for preparing Nitrogen gas in industrial processes such as the Haber Process are very specific. The correct answer choice is C. Catalyst: Iron, Promoter: Platinum. Iron is used as the primary catalyst in the Haber Process to combine hydrogen and nitrogen to make ammonia, which is a precursor for creating nitrogen gas. Platinum can act as a promoter to enhance the activity of the iron catalyst.
