In a reaction:
`CH_3COOCH_3 (aq) + OH^(-) (aq) to CH_3COO (aq) + CH_3OH (aq)`
The overall order of the reaction was determined by starting with methyl acetate and hydroxide ion at the same concentrations, so
`[CH_3COOCH_3] = [OH^-] = x`
Then rate = `k [CH_3COOCH_3]^m [OH]^n = kx^(m+n)`.
Determine the overall order and the value of rate constant, k, from the following data:
