Question

Promoter is added to the catalyst to improve its

• A. Sensitivity
• B. Porosity
• C. Surface area
• D. Surface tension

Hint:

A promoter is added in small quantity to improve the activity or performance of a catalyst.

Answer 1

The Correct Option is A

A catalyst increases the rate of a chemical reaction without being consumed. Sometimes, a small amount of another substance is added to improve the performance of the catalyst. This substance is called a promoter. A promoter itself may not show strong catalytic activity. But it improves the activity, selectivity, or sensitivity of the main catalyst. In industrial catalysis, promoters help the catalyst perform better under reaction conditions. They may improve the number of active sites or make the catalyst more effective. According to the given options, promoter is added to improve: \[ \text{sensitivity} \] Therefore, the correct answer is: \[ \text{Sensitivity} \]
