The bromination of acetone that occurs in acid solution is represented by this equation. CH COCH aq Br aq CH COCH Br aq H aq Br aq -> These kinetic data were obtained for given reaction concentrations. Initial Concentrations, M [CH3COCH3] [Br2] [H+] Initial rate, disappearance of Br2, Ms–1 0.30 0.05 0.05 5.7 10 x 0.30 0.10 0.05 5.7 10 x 0.30 0.10 0.10 1.2 10 x 0.40 0.05 0.20 3.1 10 x Based on these data, the rate equations is: (AIPMT 2008)

Rewriting the given data for the reaction 3 3 2 3 2 H CH COCH aq Br aq CH COCH Br aq H aq Br aq -> Initial concentratio n of 3 3 CH COCH in M Initial concen tration of Br2 in M Initial concentratio n of H+ in M Rate of disappearan ce of Br2 in MS–1 i.e. 2 d Br dt or dx dt 0.30 0.05 0.05 5 5.7 10 x 0.30 0.10 0.05 5 5.7 10 x 0.30 0.10 0.10 4 1.2 10 x 0.40 0.05 0.20 4 3.1 10 x Actually this reaction is autocatalyzed and involves complex calculation for concentration terms. We can look at the above results in a simple way to find the dependence of reactio
