13.74 Methyl acetate, CH,COOCH3, reacts in basic solu- tion to give acetate ion, CH;COO , and methanol, CH,OH. CH,COOCH,(ag) + OH (ag) → CH;COO (ag) + CH;OH(aq) The overall order of the reaction was determined by start- ing with methyl acetate and hydroxide ion at the same con- centrations, so [CH,COOCH3] = [OH]= x. Then Rate = k[CH,COOCH;"[OH¯]" = kx"*n %3D %3D Determine the overall order and the value of the rate con- stant by plotting the following data assuming first- and then second-order kinetics.
