Transcribed Image Text: 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

Determine the overall order and the value of the rate con-
stant by plotting the following data assuming first- and
then second-order kinetics.
