QJEEM22Chfbd1: JEE Main 2022 Chemistry - Class 11 JEEM22Chfbd1 Solution: The highest industrial consumption of molecular hydrogen is to…

Hydrogen combines with nitrogen to produce Ammonia in Haber's process.

$\mathrm{N}_{2}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{g}) \rightleftharpoons 2 \mathrm{NH}_{3}(\mathrm{g})$

In this process, iron oxide is used with small amounts of $\mathrm{K}_{2} \mathrm{O}$ and $\mathrm{Al}_{2} \mathrm{O}_{3}$ to increase the rate of attainment of equilibrium.

Optimum conditions for the production of ammonia are a pressure of $200 \mathrm{~atm}$ and a temperature of $700 \mathrm{~K}$ .

Earlier, iron was used as a catalyst with molybdenum as a promoter in this reaction.
