The chlorination of benzene can be carried out by allowing benzene to react with $mathrm{Cl}_{2}$ in the presence of $mathrm{AlCl}_{3} .$ $mathrm{Cl}_{2}$ and $mathrm{AlCl}_{3}$ react to form $mathrm{Cl}^{+} mathrm{AlCl}_{4}^{-}$. Sketch the reaction profile for the reaction of benzene and $mathrm{Cl}^{+} mathrm{AlCl}_{4}^{-}$. Use the same assumptions as in Exercise 35.
