(i) Catalyst alters the rate of reaction by lowering the activation energy. It increases the rate of reaction. (ii) Molecularity of a reaction cannot be fraction or zero. It can have value 1, 2 and 3. (iii) Energetically favourable reactions are sometimes slow because there is not proper orientation always during collision of molecules. (iv) e-Ea/RT : Arrhenius equation refers to the fraction of molecules with energy equal to or greater than activation energy. |
