The oxidation of iodide ion by the hypochlorite ion in the presence of hydroxide ions

was studied at 25°C, and the following initial rates data (Y. Chia and R. E. Connick, Journal of Physical Chemistry, Vol. 63, p. 1518, 1959) were collected:

(a) Determine the rate law for this reaction.
(b) One mechanism that has been proposed for this reaction is the following:

Show that the rate law predicted by this mechanism matches the experimentally determined rate law in part a. (Note that when writing the expression for K, the equilibrium constant, [H₂O] is not involved. See Chapter 15.)
