From the potential energy diagrams, the statement (d) is not correct, i.e., diagram (IV) has not the largest rate constant for an endothermic reaction.

Q. The potential energy diagrams for four reactions are given below Which one of the following statements about these diagrams is incorrect?

I has the largest rate constant for an exothermic reaction.

II has the smallest rate constant for the reverse reaction.

III will have the most rapid establishment of equilibrium.

IV has the largest rate constant for an endothermic reaction.

The magnitude of the enthalpy of reaction I is greater than that of III.

From the potential energy diagrams, the statement (d) is not correct, i.e., diagram (IV) has not the largest rate constant for an endothermic reaction.
