In some cases, the rate law of a reaction depends on the concentration of three reactants. Such is the case for the reaction below: Br03(aq) + 5 Br(aq) 6 H(aq) 3 Br2(aq) + 3 H201) The order with respect to each reactant can also be determined via the method of initial rates. The experimental runs to be compared must be chosen carefully wherein the concentrations of the other two reactants will not affect the rate of the reaction. Using the set of experimental runs below, determine the rate law, overall order, and the rate constant of the given reaction.
