Chemistry - Chemical Kinetics Question with Solution | TestHub

Activation energy is defined as the minimum amount of extra energy required by a reacting molecule to get converted into a product.  If${\mathrm{E}}_{\mathrm{a}}=0$ , then according to Arrhenius equation $\mathrm{k}={\mathrm{Ae}}^{-{\mathrm{E}}_{\mathrm{a}}/\mathrm{RT}}={\mathrm{Ae}}^0=\mathrm{A}$ . This implies that every collision results into a chemical reaction which cannot be true. So, a reaction cannot have zero activation energy.
