According to the adsorption theory of catalysis, the rate of reaction increases with the use of a catalyst because:

  1. the heat liberated during adsorption increases the rate of reaction
  2. the kinetic energy of reactants increases which increases the rate of reaction
  3. the activation energy of reaction increases which increases the rate of reaction
  4. the concentration of reactants at the active centers becomes high due to adsorption the rate of reaction
