Anything which increases rate of reaction without being involved in the reaction________________?
Correct answer: B. Catalyst
- A. Promoter
- B. Catalyst
- C. Inhibitor
- D. All of the above
Explanation
A catalyst increases reaction rate by providing an alternative pathway with lower activation energy and is regenerated by the end of the reaction. It participates in the mechanism but is not permanently consumed. Students may choose a because a promoter can enhance a catalyst, but a promoter is not the general name for a substance that directly catalyses the reaction.
