What is the role of a promoter in catalysis?
Correct answer: C. It is a substance that increases the efficiency of a catalyst
- A. It is the main catalyst
- B. It deactivates the catalyst
- C. It is a substance that increases the efficiency of a catalyst
- D. It is the solid support for the catalyst
Explanation
A promoter is a substance that is added to a catalyst to improve its performance. While it may have little to no catalytic activity on its own, it enhances the activity, selectivity, or stability of the main catalyst.
