Q. For a reaction $A \rightarrow B$, enthalpy of reaction is $-4.2\, kJ\, mol ^{-1}$ and enthalpy of activation is $9.6 \,k J\, mol ^{-1}$. The correct potential energy profile for the reaction is shown in option.

NEETNEET 2021Chemical Kinetics

Solution:

It is an exothermic reaction
For exothermic reaction, energy of reactants is greater than energy of products. By inspection option $3$ is correct.
