Question

what is meant by positive catalyst and negative catalyst ​

Answer 1

Answer:

Positive catalyst: A catalyst which increases the rate of reaction is called positive catalyst. Such catalyst decreases activation energy by accepting a smaller path, so rate of reaction is increased. Negative catalyst (Inhibitor): A catalyst which decreases or retards the rate of reaction is called negative catalyst.

Answer 2

Explanation:

Positive catalyst: A catalyst which increases the rate of reaction is called positive catalyst. Such catalyst decreases activation energy by accepting a smaller path, so rate of reaction is increased.

Negative catalyst (Inhibitor): A catalyst which decreases or retards the rate of reaction is called negative catalyst. It is because a negative catalyst increases activation energy by taking a longer alternative path. Also, it combines with reactant molecules and decreases the number of colliding reactant molecules.
