Question

The Bosch process is used for the large-scale production of hydrogen. Write a balanced reaction.

Answer 1

Balanced equation

• A balanced equation involves an equal number of atoms for each element on the reactant and product side.

Bosch process

• In the first step of the Bosch process, the formation of water gas takes place.
• The mixture of carbon monoxide and hydrogen gas is known as water gas or syngas.

${\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\mathrm{C}\left(\mathrm{s}\right)\underset{\mathrm{Ni}}{\overset{{1200}^{°}\mathrm{C}}{\to }}\mathrm{CO}\left(\mathrm{g}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)$

• In the second step, the water gases mix with the excess steam and formation of carbon dioxide and hydrogen gas.
• $\mathrm{CO}\left(\mathrm{g}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\underset{{450}^{°}\mathrm{C}}{\overset{{\mathrm{Fe}}_2{\mathrm{O}}_3+{\mathrm{Cr}}_2{\mathrm{O}}_3}{\to }}{\mathrm{CO}}_2\left(\mathrm{g}\right)+2{\mathrm{H}}_2\left(\mathrm{g}\right)$
