Question

Name the following:

Raw materials used in the preparation of ammonia.

Answer 1

• Pure dry nitrogen $\left({\mathrm{N}}_2\right)$ and hydrogen gas $\left({\mathrm{H}}_2\right)$ on reaction under high temperature and high pressure conditions produces ammonia gas $\left({\mathrm{NH}}_3\right)$.
• The reaction involved is:

${\mathrm{N}}_2\left(\mathrm{g}\right)\uparrow +3{\mathrm{H}}_2\left(\mathrm{g}\right)\uparrow \stackrel{\text{Fe,}500°\mathrm{C},250\mathrm{atm}}{\rightleftharpoons }2{\mathrm{NH}}_3\left(\mathrm{g}\right)\uparrow +22,400\mathrm{cal}$

• Raw materials used in the preparation of ammonia are nitrogen and hydrogen gas.
