Question
### Experimental Procedure and Calculations for Reaction Rates #### Problem Statement 2. **Solution Mixing Experiment:** - A student mixed the following solutions: - 6.0 mL of 0.0100 M \( \text{H}_2\text{SO}_3 \) - 95.0 mL of distilled water - 9.0 mL of 0.01500 M \( \text{KIO}_3 \) 2.a. **Calculating the Concentration of \( \text{SO}_3^{2-} \) after Mixing:** - What is the concentration of \( \text{SO}_3^{2-} \) after the mixing process is complete? 2.b. **Calculating the Concentration of \( \text{IO}_3^- \) after Mixing:** - What is the concentration of \( \text{IO}_3^- \) after mixing? 3. **Reaction Rate Analysis:** - After mixing the solutions described in question 2, the reaction took 46 seconds to complete (before any color change occurred). - Question: What is the rate of the reaction? ##### Explanation of Calculations: - **Step 1: Total Volume Calculation:** - Total Volume \( V_{\text{total}} = 6.0 \, \text{mL} + 95.0 \, \text{mL} + 9.0 \, \text{mL} = 110.0 \, \text{mL} \) - **Step 2: Initial Molarities:** - Initial molarity of \( \text{H}_2\text{SO}_3 \): \( 0.0100 \, \text{M} \) - Initial molarity of \( \text{KIO}_3 \): \( 0.01500 \, \text{M} \) - **Step 3: Calculate the Moles:** - Moles of \( \text{H}_2\text{SO}_3 \): \( (0.0100 \, \text{M}) \times (6.0 \, \text{mL}) = 0.060 \, \text{mmol} \) - Moles of \( \text{KIO}_3 \): \( (0
