Question : 13 of 50

Marks: +1, -0

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

adsorption lowers the activation enegry 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
adsorption produces heat which increases the speed of the reaction
