Iodide ion is oxidized in acidic solution to triiodide ion (I₃^-) by hydrogen peroxide according to the reaction H₂O₂(aq) + 3I^-(aq) +2H⁺ -> I₃^- (aq)+2H₂O(

) A series of experiments was run at different concentrations, and the initial rates of triiodide ion formation were determined:

Expt	Init H₂O₂	Init I^-	Init H⁺	Init Rate
1	0.010	0.010	0.00050	1.15x10^-6
2	0.020	0.010	0.00050	2.30x10^-6
3	0.010	0.020	0.00050	2.30x10^-6
4	0.010	0.010	0.00100	1.15x10^-6

where all concentrations are in moles/liter, and all rates are in moles/(liter-second). What is the order of the reaction with respect to hydrogen peroxide?
