During water-gas shift reaction
- (A)carbon monoxide is oxidized to carbon dioxide.✓ Correct
- (B)carbon is oxidized to carbon monoxide.
- (C)carbon dioxide is reduced to carbon monoxide.
- (D)water is evaporated in presence of catalyst.
Answer: (A)
Solution
The water-gas shift reaction is . The oxidation number of carbon rises from in CO to in , while that of hydrogen falls from in water to in . Water is thus the oxidising agent, and carbon monoxide is oxidised to carbon dioxide.
