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

Options

  1. Aadsorption lowers the activation enegry of the reaction
  2. Bthe concentration of reactant molecules at the active centres of the catalyst becomes high due to adsorption
  3. Cin the process of adsorption, the activation energy of the molecules becomes large
  4. Dadsorption produces heat which increases the speed of the reaction

Correct answer

A. adsorption lowers the activation enegry of the reaction

Step-by-step solution

In heterogeneous catalysis, adsorption lowers the activation energy of the reaction.
