NEET Chemistry Chemical Kinetics Questions Solved


The bromination of acetone that occurs in acid solution is represented by this equation.

CH3COCH3(aq) + Br2(aq)            CH3COCH2Br(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

                        5.7X10-5

                        5.7X10-5

                        1.2X10-4

                        3.1X10-4

Based on these data, the rate equation is

(a) Rate = k [CH3COCH3] [H+]

(b) Rate = k [CH=COCH3][Br2]

(c) Rate = k [CH3COCH3][Br2][H+]2

(d) Rate = k [CH3COCH3][Br2][H+]
