Which of the following factors are responsible for the increase in the rate of a surface catalyzed reaction?
(i) A catalyst provides proper orientation for the reactant molecules to react.
(ii) The heat of adsorption of reactants on a catalyst helps reactant molecules to overcome activation energy.
(iii) The catalyst increases the activation energy of the reaction.

Question

Filo · Accepted Answer

Catalyst orients the molecules properly, so that reaction occurs

The heat of adsorption of reactant molecules on a catalyst helps reactants to overcome the activation energy

A catalyst increases the rate of reaction by decreasing the energy of activation.
Hence (i) and (ii) are the correct options.
