Chlorine dioxide, ClO2, is a reddish-yellow gas that is soluble in water. In basic solution it gives ClO3  and ClO2  ions.
2ClO2(aq) 2OH(aq) → ClO3(aq) + ClO2 (aq) + H2O
To obtain the rate law for this reaction, the following experiments were run and, for each, the initial rate of reaction of ClO2 was determined. Obtain the rate law and the value of the rate constant.
