According produces to the adsorption theory of catalysis, the speed of the reaction increases because

Answer»

Adsorption produces heat which increases the speed of the reaction
Adsorption LOWERS the activation energy of the reaction
The CONCENTRATION of REACTANT molecules at the active centres of the CATALYST becomes high due to adsorption
In the process of adsorption, the activation energy of the molecules becomes large
