Four experiments were conducted to discover how the initial rate of consumption of BrO3- ions in the reaction BrO3-(aq) + 5Br-(aq) + 6H+(aq) à 3Br2(aq) + 3H2O(l) varies as the concentration of the reactants are changed. Use the data given below to determine the average rate constant and write the rate law for this reaction. Experiment [BrO3-] (M) [Br-] (M) [H+] (M) Initial rate (M/s) 1 0.10 0.10 0.10 0.0012 2 0.20 0.10 0.10 0.0024 3 0.10 0.30 0.10 0.0035...
