Solution

The correct option is A True
A catalyst is a substance which accelerates the rate of a chemical reaction without undergoing any change in its chemical composition or mass during the reaction. A catalyst accelerates the rate of a reaction by lowering the activation energy.
Substances which themselves are not catalysts but when mixed in small quantities with the catalysts increase their efficiency are called as Promoters.
