A) absorption 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
Correct Answer: B
Solution :
According to adsorption theory of catalysis, the speed (rate) of the reaction increase because adsorption lowers the activation energy of the reaction \[(\because \,Rate\,of\,reaction\,\propto \,\frac{1}{activation\,energy})\]
