This question relates to the industrial manufacture of Hydrogen.

(i) Name the process.

(ii) Give the main reactions with conditions.

(i) Bosch process

(ii) The main reactions of Bosch process are :

Step I

Reaction : Production of water gas

$\underset{\text{coke}}{\text{C}} + \underset{\text{steam}}{\text{H}$2\text{O}} \xrightarrow{1000 \degree \text{C}} \underset{\text{water gas}}{[\text{CO} + \text{H}2 ]} - \Delta

Step II

Reaction : Reduction of steam to hydrogen - by carbon monoxide

$\underset{\text{water gas}}{[\text{CO} + \text{H}$2 ]} + \underset{\text{excess steam}}{\text{H}2\text{O}} \xrightarrow[\text{Fe}2\text{O}3]{450 \degree \text{C}} \text{CO}2 + 2\text{H}2 + \Delta
