Question

For the reaction \[ CO + 2H_2 \xrightarrow{\text{catalyst}} CH_3OH, \] the catalyst used is

• A. Fe
• B. Cr$_2$O$_3$/ZnO
• C. V$_2$O$_5$
• D. Al$_2$O$_3$

Hint:

Remember catalyst–process matching in communication systems.

Answer 1

The Correct Option is B

Step 1: Industrial methanol synthesis utilizes a mixed catalyst of chromium oxide promoted zinc oxide.
Step 2: Other options: - Fe – used in Haber process. - Al$_2$O$_3$ – dehydrating catalyst. - V$_2$O$_5$ – contact process.
Step 3: Therefore only (B) fits. Hence → (B).
