2icl + h2i2 + 2 hcl is first order in icl and second order in h2. complete the rate law for this reaction in the box below. use the form , where '1' is understood for m, n (don't enter 1) and concentrations taken to the zero power do not appear. rate = in an experiment to determine the rate law, the rate constant was determined to be 2.01 m-2s-1. using this value for the rate constant, the rate of the reaction when [icl] = 0.273 m and [h2] = 0.217 m would be ms-1.
