Question

Which promoter is used in Haber's process?

Answer 1

Haber's process:

• Industrial manufacturing of ammonia $\left({\mathrm{NH}}_3\right)$ is done through Haber's process.
• In this process, Nitrogen$\left({\mathrm{N}}_2\right)$ and Hydrogen $\left({\mathrm{H}}_2\right)$are taken in a ratio of $1:3.$
• Then under high pressure of $200\mathrm{atm}$ and low temperature of $400\mathrm{K}$the reaction yields Ammonia.

• The promoter that we use here is “Molybdenum”, as it increases the efficiency of the catalyst Iron and resulting in a higher ammonia yield.

Liquid Ammonia is obtained through this process.

${\mathrm{N}}_2\left(\mathrm{aq}\right)+3{\mathrm{H}}_2\left(\mathrm{aq}\right)\rightleftharpoons 2{\mathrm{NH}}_3\left(\mathrm{aq}\right)$
