Question
**Kinetic Study of Hydrogen Peroxide Reaction with Iodide Ion and Hydrogen Ion**

In this experiment, the kinetic data were collected for the reaction of hydrogen peroxide (\( \text{H}_2\text{O}_2 \)) in an aqueous solution with iodide ions (\( \text{I}^- \)) and hydrogen ions (\( \text{H}^+ \)). The reaction sequence is as follows:

\[ \text{H}_2\text{O}_2(aq) + 3 \text{I}^-_{(aq)} + 2 \text{H}^+_{(aq)} \rightarrow \text{I}_3^-_{(aq)} + 2 \text{H}_2\text{O}_{(l)} \]

The experimental data are presented in the table below:

| Exp. | [H2O2], M | [I-], M | [H+], M | Initial Rate, M/s |
|------|-----------|--------|---------|-------------------|
| 1    | 0.010     | 0.010  | 0.00050 | 1.15 x 10^-6      |
| 2    | 0.020     | 0.010  | 0.00050 | 4.60 x 10^-6      |
| 3    | 0.010     | 0.020  | 0.00050 | 1.15 x 10^-6      |
| 4    | 0.010     | 0.010  | 0.00100 | 2.30 x 10^-6      |

**Objective:**

Determine the rate law for this reaction.

**Options:**

1. \( \text{R} = 0.0115 \text{ M}^{-1} \text{ s}^{-1} [\text{H}_2\text{O}_2][\text{I}^-] \)
2. \( \text{none of the answers are correct} \)
3. \( \text{R} = 2.3 \text{ M}^{-2} \text{ s}^{-1} [\text{H}_2\text{O}_2]^2 [\text{H}^+] \)
4. \( \text{R} = 1
