According to the adsorption theory of catalysis, the speed of the reaction increases because
  • a)
    the conc. of reactant molecules at the active centres of the catalyst becomes high due to adsorption
  • b)
    in the process of adsorption the activation energy of the molecules becomes large
  • c)
    adsorption produces heat which increases the speed of the reaction
  • d)
    adsorption lowers the activation energy of the reaction
Correct answer is option 'D'. Can you explain this answer?

Adsorption Theory of Catalysis:

Explanation:
Adsorption theory of catalysis explains that the speed of a reaction increases when a catalyst is present due to the process of adsorption.

Key Points:
1. Adsorption of reactant molecules onto the surface of the catalyst increases the concentration of reactant molecules at the active sites of the catalyst.
2. This high concentration of reactant molecules at the active sites lowers the activation energy required for the reaction to occur.
3. As a result, adsorption lowers the overall activation energy of the reaction, making it easier for the reaction to proceed.
4. Lowering the activation energy increases the speed of the reaction, as more reactant molecules can overcome the energy barrier and participate in the reaction.
5. Therefore, the correct answer is option 'D' - adsorption lowers the activation energy of the reaction, leading to an increase in the speed of the reaction.
In conclusion, the adsorption theory of catalysis provides a mechanism for understanding how catalysts increase the speed of reactions by lowering the activation energy through the process of adsorption.
