Question:

The equation that represents the water-gas shift reaction is :

1. $\mathrm{CO}(\mathrm{g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \underset{\text { Catalyst }}{\stackrel{673 \mathrm{~K}}{\longrightarrow}} \mathrm{CO}_{2}(\mathrm{~g})+\mathrm{H}_{2}(\mathrm{~g})$

2. $\mathrm{CH}_{4}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \stackrel{1270 \mathrm{~K}}{\mathrm{Ni}} \mathrm{CO}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{~g})$

3. $\mathrm{C}(\mathrm{s})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \stackrel{1270 \mathrm{~K}}{\longrightarrow} \mathrm{CO}(\mathrm{g})+\mathrm{H}_{2}(\mathrm{~g})$

4. $2 \mathrm{C}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{~g})+4 \mathrm{~N}_{2}(\mathrm{~g}) \stackrel{1273 \mathrm{~K}}{\longrightarrow} 2 \mathrm{CO}(\mathrm{g})+4 \mathrm{~N}_{2}(\mathrm{~g})$

Correct Option: 1

Solution:

(1) Water gas shift reaction

$\mathrm{CO}_{(\mathrm{g})}+\mathrm{H}_{2} \mathrm{O}_{(\mathrm{g})} \frac{673 \mathrm{~K}}{\text { catalyst }} \mathrm{CO}_{2(\mathrm{~g})}+\mathrm{H}_{2(\mathrm{~g})}$

(2) Water gas is produced by this reaction.

$\mathrm{CH}_{4(\mathrm{~g})}+\mathrm{H}_{2} \mathrm{O}_{(\mathrm{g})} \stackrel{1270 \mathrm{~K}}{\mathrm{Ni}} \mathrm{CO}_{(\mathrm{g})}+3 \mathrm{H}_{2(\mathrm{~g})}$

(3) Water gas is produced by this reaction

$\mathrm{C}_{(\mathrm{s})}+\mathrm{H}_{2} \mathrm{O}_{(\mathrm{g})} \stackrel{1270 \mathrm{~K}}{\longrightarrow} \mathrm{CO}_{(\mathrm{g})}+\mathrm{H}_{2(\mathrm{~g})}$

(4) producer gas is produced by this reaction.

$2 \mathrm{C}_{(\mathrm{s})}+\mathrm{O}_{2(\mathrm{~g})}+4 \mathrm{~N}_{2(\mathrm{~g})} \stackrel{1270 \mathrm{~K}}{\longrightarrow} 2 \mathrm{CO}_{(\mathrm{g})}+4 \mathrm{~N}_{2(\mathrm{~g})}$
