Question:
Identify catalyst used in following reaction.
$CO_{(g)} + H_2O_{(g)} \xrightarrow{623\text{ K}} CO_{2(g)} + H_{2(g)}$
Identify catalyst used in following reaction.
$CO_{(g)} + H_2O_{(g)} \xrightarrow{623\text{ K}} CO_{2(g)} + H_{2(g)}$
$CO_{(g)} + H_2O_{(g)} \xrightarrow{623\text{ K}} CO_{2(g)} + H_{2(g)}$
Show Hint
Water-gas shift reaction: $CO + H_2O \rightarrow CO_2 + H_2$. Catalyst: Iron Chromate.
Updated On: Apr 30, 2026

- Traces of acid or alkali
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Identification
This reaction is the Water-Gas Shift Reaction, used to produce industrial hydrogen.
Step 2: Analysis
The reaction of Carbon monoxide with steam at $623\text{ K}$ is catalyzed by oxides of transition metals.
Step 3: Conclusion
Iron chromate ($FeCrO_4$) is the standard catalyst used for this industrial process.
Final Answer: (A)
