NEETChemistryChemical KineticsMCQ+4 / −1
The bromination of acetone that occurs in acid solution is represented by this equation.
CH3COCH3(aq) + Br2(aq)  →\to→
     CH3COCH2Br(aq) + H+(aq) + Br−-−(aq)
These kinetic data were obtained for given reaction concentrations.
Initial concentrations, M
[CH3COCH3 [Br2] [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 Br2, Ms−-−1
5.7×\times×10−-−5
5.7×\times×10−-−5
1.2×\times×10−-−4
3.1×\times×10−-−4

Based on these data, the rate equation is
  1. A
    Rate = k[CH3COCH3][Br2][H+]2
  2. B
    Rate = k[CH3COCH3][Br2][H+]
  3. C
    Rate = k[CH3COCH3][H+]
  4. D
    Rate = k[CH3COCH3][Br2]
