Question

How is ammonia synthesized? Write the chemical equation

Answer 1

• Ammonia is produced by the Haber-Bosch process. In this process,
• Nitrogen and Hydrogen in the ratio 1:3 by volume is compressed to 200-300 atmospheric pressure and passed over a finely divided iron at 300⁰C. The ammonia gas formed is cooled to obtain liquid ammonia

$$\begin{gathered} {\mathrm{N}}_2\left(\mathrm{g}\right)+3\mathrm{H}{}_2\left(\mathrm{g}\right)\underset{200-300\mathrm{atm}\mathrm{pressure}}{\overset{300-{450}^0\mathrm{C}}{\to }}2{\mathrm{NH}}_3\left(\mathrm{g}\right) \\ \left(\mathrm{Nitrogen}\right)\left(\mathrm{Hydrogen}\right)\left(\mathrm{Ammonia}\right) \end{gathered}$$
