During water-gas shift reaction
Options
- ACarbon monoxide is oxidized to carbon dioxide.
- BWater is evaporated in presence of catalyst.
- CCarbon is oxidized to carbon monoxide.
- DCarbon dioxide is reduced to carbon monoxide.
Correct answer
A. Carbon monoxide is oxidized to carbon dioxide.
Step-by-step solution
The reaction between CO of syn gas and steam in presence of catalyst is called water gas shift reaction. CO + H 2 O → CO 2 + H 2 O This reaction increases the yield of hydrogen obtained from coal gasification reaction as shown below. C + H 2 O ⟶ CO + H 2 ⏟ syn   gas
