According to the ad sorption theory of catalysis, the speed of the reaction increases because- [2003]
  • a)
    Adsorption lowers the activation energy of the reaction
  • b)
    The concentration of reactant molecules at the active centres of the catalyst becomes high due to strong adsorption
  • c)
    In the process of adsorption, the activation energy of the molecules becomes large
  • d)
    Adsorption produces heat which increases the speed of the reaction
Correct answer is option 'A'. Can you explain this answer?

According to the adsor ption theory of catalysis, the activity of catalysis is due to the presence of free valencies on its surface due to which surface of catalyst has chemical force of altraction. When a gas comes in contact with this surface molecules get attached attached through these valencies.
Further the rate of reaction is always increases by decreases in activation energy When any of the reactants is strongly adsorbed on the surface of catalyst, the rate becomes inversely proportional to the concentration of that reaction. The reaction is then said to be inhibited by such reactant.
The lowering of activation energy always leads to the increase in speed of reaction.

Adsorption causes decrease in surface energy which appears as heat. Thus adsorption is an exothermic process and hence lowers the activation energy of the reaction.
