For the reaction show below determine the rate law.
CH3COCH3 + Br2 → CH3COCH2Br + HBr(aq)
The bromination of acetone, an organic solvent, is catalyzed by an acid. The rate of disappearance of bromine was measured for several different concentrations of the reactants including the catalyst, H+. Therefore, the catalyst will appear in the rate law, but not in the overall reaction. The following data were obtained:
[CH3COCH3] [Br2] [H+] Initial Rate (mol/L s)
0.30 0.05 0.05 5.7 x 10-5
0.30 0.10 0.05 5.7 x 10-5
0.30 0.05 0.10 11.7 x 10-5
0.40 0.05 0.05 7.6 x 10-5
Calculate the rate law for this reaction: rate = k [CH3COCH3][ ] [Br2][ ] [H+][ ]
