–overall order and value of rate constant Methyl acetate, CH3COOCH3, reacts in basic solution to give acetate ion, CH3COO-, and methanol, CH3OH. CH3COOCH3 (aq) + OH- (aq) ? CH3COO- (aq) + CH3OH (aq) The overall order of the reaction was determined by starting with methyl acetate and hydroxide ion at the same concentrations, so [CH3COOCH3] […]
