Question

A catalyst remains unchanged during the reaction :

• A. True
• B. False

Answer 1

The correct option is A True

Catalyst is defined as the substance which alters the rate of reaction that is either decrease or increase without being incorporated into the product. Here catalyst alters the reaction by forming either a layer on the reactant or acts on one material to activate it towards reaction with another material that it would not otherwise spontaneously react with (it lowers the reaction's activation barrier). Hence it does not involve. Hence the given statement is true.
