Question:
During water-gas shift reaction
During water-gas shift reaction
Show Hint
The water-gas shift reaction is a key industrial process for hydrogen production. It converts CO and H2O into CO2 and H2
Updated On: Jan 16, 2025
- carbon is oxidized to carbon monoxide
- carbon monoxide is oxidized to carbon dioxide.
- carbon dioxide is reduced to carbon monoxide
- water is evaporated in presence of catalyst.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The water-gas shift reaction is:
\[ CO + H_2O \rightarrow CO_2 + H_2 \]
Key Points:
- Oxidation: Carbon monoxide (\( CO \)) is oxidized to carbon dioxide (\( CO_2 \)).
- Reduction: Water (\( H_2O \)) is reduced to produce hydrogen gas (\( H_2 \)).
- Catalyst: The reaction typically occurs in the presence of a catalyst such as iron oxide (\( Fe_3O_4 \)) with chromium oxide as a promoter.
Applications:
- Widely used in hydrogen production for fuel cells and ammonia synthesis.
- Helps remove carbon monoxide from industrial gas streams.
