Substances which alter the velocity of a reaction by mere presence, without undergoing any change in mass and compossition are termed catalyst and the phenomenon is known as catalysis
According to the adsorption theroy of catalysis, the rate of reaction increases because

A

adsorption lowers the activation energy of the reaction

B

concentration of reactant molecules at the active centres of the catalyst becomes high due to adsorption

C

adsorption produces heat which increases the rate of reaction
