Compare the rates and determine the orders of the reaction with respect to the iodide ion and hydrogen peroxide. Round the orders to the nearest integer and write the rate law. given : the rate law for the reaction of the form : rate=k [I-]*[H2O2]y ( in which K is the rate constant for the reaction and x and y are the orders of the reaction with respect to the iodide ion and the hydrogen peroxide , respectively.rate of reaction of run #1 : 1.08*10^-6 M.s^-1rate of reaction of run #2 : 1.58*10^-6 M.s^-1rate of reaction of run #3: 1.99*10^-6 M.s^-1 ### Chemistry Experiment: Determination of the Rate Law**Materials and Quantities:**- **Mass of potassium iodide used:** 0.12g- **Mass of sodium thiosulfate pentahydrate used:** 0.115g- **Volume of 30% hydrogen peroxide:** 2 ml### Part A: Rate Law Determination**Temperature:** (Temperature not provided)#### Data Collection (for three runs):| | Run #1 | Run #2 | Run #3 ||-------------------|------------------------|------------------------|------------------------|| **Time until permanent blue color appears** | 1.08 x 10⁻³ (s⁻¹) | 1.58 x 10⁻⁶ (s⁻¹) | 1.99 x 10⁻⁶ (s⁻¹) || **Rate of reaction** | | | || **Rate law** | | | || **Rate constant** | | | || **Temperature of solution** | | | |### Calculations:- **Volume Calculation for Hydrogen Peroxide:** \[ 3 = V_1T_1 + V_2 \times 30 \\ 3 = V_1 / 20 \times 30 \\ V_1 = (3 \times 20) / 30 = 2 \, ml \]- **Reaction Calculations:** \[ 0.025 \, \text{mol} / l \times (50 \, ml \times 1 / 1000 \, ml) \\ = 0.025 \, \text{mol} / l \times 0.050 \, l \\ = 0.00125 \, \text{mol} \\ 0.00125 \, \text{mol} \times 166.9 \, \text{g/mol} = 0.2 \, g \\ \]These calculations are used to determine various parameters such as the rate constant and rate law for the reaction. The rate of reaction is calculated based on the time taken for a permanent blue color to appear in multiple runs.This experimental setup and the associated reactions demonstrate the ### Experimental Procedure: Reaction Rates and Temperature Effects#### Components for Each Run| Components | Run #1 | Run #2 | Run #3 ||-----------------------------|--------|--------|--------|| 0.36 M sulfuric acid | 35 mL | 35 mL | 35 mL || Deionized water | 48 mL | 43 mL | 47 mL || 0.025 M potassium iodide | 5 mL | 10 mL | 5 mL || 0.0025 M sodium thiosulfate | 10 mL | 10 mL | 10 mL || Starch solution | 1 mL | 1 mL | 1 mL |#### Part A: Reaction Time Measurement1. **Add Components:** For **Run #1**, mix the components in the order provided in the above table. Ensure thorough mixing before proceeding to the subsequent steps.2. **Pipetting Hydrogen Peroxide:** Pipette 1.0 mL of 3% hydrogen peroxide into the flask and note the time of addition (3% hydrogen peroxide is equivalent to 0.88 M hydrogen peroxide).3. **Swirl and Observe:** Swirl the flask continuously and measure the time required, to the nearest second, for a permanent blue-black color to appear. This indicates the reaction is complete. Record this time.4. **Temperature Measurement:** Measure the temperature of the solution.5. **Repeat Steps for Run #2:** Perform the steps 1 to 4 using the components listed under **Run #2**.6. **Run #3 Protocol:** For **Run #3**, pipette 2.0 mL of 3% hydrogen peroxide and note the time of addition.7. **Observe and Record:** Similarly, swirl the flask and record the time taken for the blue-black color to appear, indicating the end of the reaction.#### Part B: Temperature Effect1. **Temperature Variation:** Repeat the reaction using the same amounts of reactants as used for **Run #3** but at different temperatures. Use an ice bath to achieve temperatures of **5-10°C** and a hot water bath for approximately **50°C
