I−(aq)+Cl−→IO−(aq)+Cl−(aq)
and the following initial concentration and initial rate data for this reaction.

Exp. No	[I−]M	[OCl−]M	Initial rate Ms−1
1.	0.1000	0.0500	3.05×10−4
2.	0.2000	0.0500	6.10×10−4
3.	0.3000	0.0100	1.83×10−4
4.	0.3000	0.0200	3.66×10−4

Which of the following is the correct rate lawfor this reaction?

Rate =k[I−]2[OCl−]
Rate =k[OCl−]
Rate =k[I−]2
Rate =k[I−][OCl−]
