Catalyst used in Haber’s process.

Answer 1

Haber’s process

• Haber’s process is the reaction between nitrogen and hydrogen in the presence of $\mathrm{Fe}$ catalyst, at high temperature and pressure and ammonia is formed in this process.
• The catalyst used can be $\mathrm{Fe}$ or $\mathrm{Mo}$.
• The reaction is given as follows:

$$\begin{gathered} {\mathrm{N}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\left(\mathrm{g}\right)\underset{300-500\mathrm{atm}}{\overset{\mathrm{Fe}/\mathrm{Mo}}{\to }}2{\mathrm{NH}}_3\left(\mathrm{g}\right) \\ \mathrm{Nitrogen}\mathrm{Hydrogen}\mathrm{Ammonia} \end{gathered}$$

• A catalyst used in the Haber’s process is $\mathrm{Fe}$.
