NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyAccording to the adsorption theory of catalysis, the speed of the reaction increase because:
| 1. | The concentration of reactant molecules at the active centers of the catalyst becomes high due to adsorption |
| 2. | In the process of adsorption, the activation energy of the molecules becomes large |
| 3. | Adsorption produces heat which increases the speed of the reaction |
| 4. | Adsorption lowers the activation energy of the reaction |
