For a reaction A → B, enthalpy of reaction is -4.2 kJ mol-1 and enthalpy of activation is 9.6 kJ mol-1. The correct potential energy profile for the reaction is shown in option. (NEET 2021) (a) (b) (c) (d)
Answer
D
Explanation
Since the enthalpy of reaction is negative, it means product has lesser potential energy than the reactant. Thus, the graph would be (d)
