B$)$ When the reaction is carried out in the presence of benzene, a mixture of two terminal $C-H$ activation products is observed. At early times A$,$ the "tuck$-$over" complex, a product of intramolecular C$-$H activation, dominates the ${?}^{1}H$ NMR spectrum, while $B,$ the product of benzene $C-H$ activation, grows in over time.

M

Draw a free energy diagram that clearly shows the kinetic and thermodynamic relationship between these three species.
