Question

Identify the catalyst used in following reaction at \(500^\circ\text{C}\) ?
\(\text{CO} + \text{H}_2\text{O} \rightleftharpoons \text{CO}_2 + \text{H}_2\)

• A. \(\text{Fe} - \text{Cr}\)
• B. \(\text{Ni}\)
• C. \(\text{Co} - \text{Th}\)
• D. Platinised asbestos

Hint:

Water gas shift reaction: \[ \text{CO}+\text{H}_2\text{O}\rightarrow \text{CO}_2+\text{H}_2 \] uses \(\text{Fe}-\text{Cr}\) catalyst at high temperature.

Answer 1

The Correct Option is A

Concept:
The reaction \[ \text{CO}+\text{H}_2\text{O}\rightleftharpoons \text{CO}_2+\text{H}_2 \] is known as the water gas shift reaction. Industrially, this reaction is carried out using iron oxide promoted with chromium oxide catalyst. ip

Step 1: Identify the name of the reaction.
This is the water gas shift reaction, used for increasing hydrogen content in industrial gas mixtures. ip

Step 2: Recall the catalyst used.
At high temperature, this reaction is carried out using: \[ \text{Fe}-\text{Cr} \] catalyst. ip Hence, the correct answer is:
\[ \boxed{(A)\ \text{Fe}-\text{Cr}} \]
