According to the adsorption theory of catalysis, the speed of the reaction increase because

Answer»

in the process of adsorption, the activation energy of the molecules becomes large
adsorption PRODUCES heat which increase the speed of the reaction.
adsorption lowers the activation energy of the reaction
the CONCENTRATION of product molecules at the active CENTRES of the catalyst becomes HIGH due to adsorption.

Solution :Adsorption lowers the activation energy.
