Question
How does a catalyst differ from reaction intermediate?
✓
Answer
A catalyst accelerates the rate of reaction, while reaction intermediate has no effect on the rate of the reaction.
The catalyst is always present at the start of the reaction whereas reaction intermediate is produced during the mechanism of the reaction.
A catalyst is consumed in one of the steps of mechanism and regenerated in a subsequent step while the reaction intermediate is formed in one step and consumed in subsequent step.
The catalyst is stable but the reaction intermediate is unstable and short lived.
