Question

Which is used in the Haber’s process for the manufacture of NH₃?

Options

• Al₂O₃

• Fe + Mo

• CuO

• Pt

Answer 1

Fe + Mo

Explanation:

In the Haber’s process for the manufacture of ammonia (NH₃), finely divided iron (Fe) is used as the catalyst, and molybdenum (Mo) acts as a promoter to enhance the catalyst’s efficiency. This combination helps to increase the rate of the reaction between nitrogen and hydrogen gases to produce ammonia.
