Adsorption lowers the activation energy of the reaction

(A) According to the adsorption theory of catalysis,the catalyst provides a surface where reactant molecules get adsorbed. This adsorption increases the concentration of reactants at the active sites and,more importantly,it provides an alternative pathway with lower activation energy,thereby increasing the rate of the reaction.

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

AIPMT 2003 All AIPMT

A
Adsorption lowers the activation energy of the reaction
B
The concentration of reactant molecules at the active centres of the catalyst becomes high due to adsorption
C
In the process of adsorption,the activation energy of the molecules becomes large
D
Adsorption produces heat which increases the speed of the reaction
