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

Options

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

Answer

B

Explanation

A catalyst lowers the activation energy of the reaction and hence accelerates the speed of the reaction. In other words,
`because` Rate of reaction
`prop(1)/("activation energy")`
further, as adsorption is exothermic, the heat released further helps to speed up-the reaction.
