The rate law for the oxidation of iodide to iodine by hydrogen peroxide in weakly acidic solution is — Kinetics Chemistry Question

The rate law for the oxidation of iodide to iodine by hydrogen peroxide in weakly acidic solution is studied by allowing the reaction to proceed in the presence of a fixed amount of sodium thiosulfate (which rapidly reduces iodine to iodide) and measuring the time t to the first appearance of a blue color due to the starch-iodine complex. The following data are obtained on solutions made with the indicated volumes of reactant solutions and enough water to give a total volume of 10.0 mL. What are the reaction orders in H₂O₂, I–, and H⁺?
H₂O₂(aq) + 2 I–(aq) + 2 H⁺(aq) → I₂(aq) + 2 H₂O(l)
