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.
