Question

Which among the following chemicals is used as a catalytic promoter in Haber’s process?

• A. Ni
• B. MnO$_2$
• C. Fe
• D. Mo

Answer 1

The Correct Option is C

The Haber-Bosch process is an industrial method for synthesizing ammonia from nitrogen and hydrogen gas. The balanced chemical equation for this reaction is:

N₂(g) + 3H₂(g) → 2NH₃(g)

Due to the robust triple bond in the nitrogen molecule, a catalyst is essential for the efficient execution of this reaction. In the Haber process, iron (Fe) serves as the primary catalyst.

The catalytic efficacy of iron can be augmented by the inclusion of a catalytic promoter. Specifically, molybdenum (Mo) functions as the catalytic promoter in this process. Molybdenum is incorporated to enhance the reactivity and durability of the iron catalyst, consequently boosting the overall process efficiency.

Consequently, from the provided options, Mo (Molybdenum) is identified as the catalytic promoter utilized in the Haber process.
