Acetic anhydride reacts with water in the following manner: CH3C(O)-O-C(O)CH3 + H2O = 2CH3CO2 If this reaction is carried out in an inert solvent with low concentrations of both acetic anhydride and water, it follows the rate law rate = k [CH3C(O)-O-C(O)CH3] [H2O] with a rate constant of 0.0035 s-1. However, if low concentrations of acetic anhydride are placed in pure water, it follows the rate law rate = K [CH3C(O)-O-C(O)CH3] where K = 0.1944 s-1. Explain why this is happening.

Peroxides are often added to free-radical reactions as initiators because the oxygen–oxygen bond cleaves homolytically rather easily. For example, the bond-dissociation enthalpy of the O¬O bond in hydrogen peroxide (H¬O¬O¬H) is only 213 kJ>mol (51 kcal>mol). Give a mechanism for the hydrogen peroxide-initiated reaction of cyclopentane with chlorine. The BDE for HO¬Cl is 210 kJ>mol (50 kcal>mol).
