The bromination of acetone that occurs in acid solution is represented by this equation
`CH_(3)COCH_(3)(aq.)rarr CH_(3)COCH_(2)Br(aq.)+H^(+)(aq.)+Br^(-)(aq.)`
These kinetic data were obtained from given reaction concentrations.
Initial concentrations, (M)
`{:("["CH_(3)COCH_(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):}`
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 :

Options

A. Rate `=k[CH_3COCH_3][Br_2][H^+]`
B. Rate `k=[CH_3COCH_3][H^+]`
C. Rate `{:(" "O),(" ||"),([CH_3-C-CH_3][Br_2]):}`
D. Rate `=k[CH_3COCH_3][Br_2][H^+]^2`

Answer

B
