A study was made of the effect of the hydroxide concentration on the rate of the reaction given below.

I ^-(aq) + OCl ^-(aq) IO^-(aq) + Cl ^-(aq)

The following data were obtained.

[I -]0 (mol/L)	[OCl -]0 (mol/L)	[OH -]0 (mol/L)	Initial Rate (mol/Ls)
0.0013	0.012	0.10	9.4 10-3
0.0026	0.012	0.10	18.7 10-3
0.0013	0.0060	0.10	4.7 10-3
0.0013	0.018	0.10	14.0 10-3
0.0013	0.012	0.050	18.7 10-3
0.0013	0.012	0.20	4.7 10-3
0.0013	0.018	0.20	7.0 10-3

Determine the rate law and the value of the rate constant for this reaction.
