Q .     The bromination of acetone that occurs in acid solution is represented by this equation . `CH_3COCH_(3( aq)) + Br_(2 (aq)) → CH_3 COCH_2Br_(aq) +H_(aq)^+ +Br_(aq)^-`

These kinetic data were obtained for given reaction concentrations

`text(Initial concentrations, M)`







`[CH_3COCH_3]` `[Br_2]` `[H^+]`
`0.30` `0.05` `0.05`
`0.30` `0.10` `0.05`
`0.30` `0.10` `0.10`
`0.40` `0.05` `0.20`


`text(Initial rate, disappearance of) Br_2 , Ms^(-1)`

`[(5.7xx10^(-5)) , (5.7xx10^(-5)) , (1.2xx10^(-4)) , (3.1xx10^(-4)) ]`

Based on these data. the rate equation is

AIPMT 2008
A

Rate ` = k [CH_3COCH_3][Br_2][H^+]^2`

B

Rate = `k [CH_3COCH_3][Br_2] [H^+]`

C

Rate `= k[CH_3COCH_3][H^+]`

D

Rate = `k [CH_3COCH_3][Br_2] `
