According to the adsoption theory of catalysis ,the speed of the reaction increases because:

A

adsorption produces heat which increases the speed of the reaction

B

adsorption lowers the activation energy 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 becomes large

Text Solution

Verified by Experts

The correct Answer is:
B
According to adsorption theory of catalysis, the speed (rate) of the reaction increases because adsorption lowers the activation energy of the reaction.
`(therefore " Rate of reaction"prop (1)/("activation energy "))`
