### Kinetics of the Reaction Between Hydrogen Peroxide and Iodide Ion

#### Experimental Data

Kinetic data were obtained on the aqueous reaction of hydrogen peroxide with iodide ion and H⁺:

\[ H_2O_2 (aq) + 3 I^{-} (aq) + 2 H^{+} (aq) \rightarrow I_3^{-} (aq) + 2 H_2O (l) \]

The following table summarizes the experimental data observed:

| Exp. | \([H_2O_2]\), M | \([I^-]\), M | \([H^+]\), M | Initial Rate, M/s       |
|------|-------------------|------------|--------------|-------------------------|
| 1    | 0.010             | 0.010      | 0.00050      | 1.15 × 10⁻⁶             |
| 2    | 0.020             | 0.010      | 0.00050      | 4.60 × 10⁻⁶             |
| 3    | 0.010             | 0.020      | 0.00050      | 1.15 × 10⁻⁶             |
| 4    | 0.010             | 0.010      | 0.00100      | 2.30 × 10⁻⁶             |

#### Determine the Rate Law for the Reaction

Using the experimental data provided, determine the rate law for the reaction. None of the given answers are correct.

### Possible Rate Law Options

- \( R = 2.3 \, M^{-2} \, s^{-1} \, [\text{H}_2\text{O}_2]_2 \, [\text{H}^+] \)
- \( R = 1.15 \times 10^{-2} \, M^{-1} \, s^{-1} \, [\text{H}_2\text{O}_2]_2 \)
- \( R = 0.0115 \, M^{-1} \, s^{-1} \, [\text{H}_2\text{O}_2] \, [\text{I}^-] \)
