Draw a labelled reaction coordinate diagram for the both SN reactions. Label the activation energy (free energy of activation) and give the approximate structures of the intimal state, the transition states, the intermediate and product at the correct points along the reaction coordinate. Also, can you decide on the basis of the kinetic expression whether the t-butyl chloride-hydroxide ion reaction proceeds by a one-step or a two-step mechanism? Explain why observed kinetic expression is consistent with the mechanism you chose.
