Question

what is used as promoter for manufacturing of NH3 by habers process

Answer 1

Molybdenum in fine powder form is used as the promoter in Habers Process.

Answer 2

Answer : Molybdenum is used as promoter for manufacturing of $NH_3$ by haber's process.

Explanation :

Haber process : It is a common industrial process used to manufacture ammonia from hydrogen and nitrogen. Nitrogen is obtained from the air, while hydrogen is obtained from natural gas.

The chemical equation is,

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

Promoter : It is a substance added to a solid catalyst to improve its performance in the chemical reaction.

Hence, the molybdenum is used as promoter for manufacturing of $NH_3$ by haber's process.
