Set up apparatus as shown in Figure

Attached is a lab for my General Chemistry II course. This lab is titled Reaction Rates. I primarily need help on the three tables and post-lab questions. I included the lab steps, for guidance. Reaction RatesExperiment 1: Calculating Rate of ReactionIn this experiment you will calculate the rate of reaction of potassium iodide and hydrogen peroxide. The order of the reaction will also be determined.Materials20 mL 3% Hydrogen peroxide, H2O215 mL Iodine-Potassium Iodide Solution, IKI (1% Iodine, 2% Potassium Iodide)100 mL Beaker10 mL Graduated cylinder100 mL Graduated cylinder 250 mL Beaker(2) 250 mL Erlenmeyer flasks 1-Hole Rubber stopper 2-Hole Rubber stopper(2) 3 in.

Set up apparatus as shown in Figure 2. To do this, begin by labeling the Erlenmeyer Flasks as 1 and 2. The reaction will take place in Flask 1.2. Fill Flask 2 approximately three quarters of the way full with water.3. Press the 2-hole rubber stopper into the top of Flask 2. Place one three in. piece and one six in. piece of rigid tubing into each hole of the rubber stopper. This should create an airtight system.Caution: Please be careful when working with rigid tubing. This tubing is made of glass and can break if excess force is applied.4. Place the one-hole stopper on Flask 1, and fit the remaining three in. piece of rigid tubing in the stopper.5. Connect Flask 1 and Flask 2 with the two, 12 in flexible tubing pieces. One piece should connect Flask 1Reaction Ratesto Flask 2, and the second piece should connect Flask 2 to the graduated cylinder (see Figure 2). The tubing which connects Flask 2 to the graduated cylinder should be positioned low enough to be im- mersed in the water in Flask 2.Part A: Preparation of Reactants1. Pour five mL of the IKI solution into a 10 mL graduated cylinder.2. Add five mL of distilled water to the graduated cylinder to bring the total volume to 10 mL. This is the0.5% – 1.0% (diluted) IKI solution.3. Pour 15 mL of 3% H2O2 solution into a 100 mL beaker.4. Add five mL of distilled water to this beaker and mix with a stir rod. This is the 2.25% (diluted) H2O2solution.Part B: Performing the Reaction1. Remove the stopper from Flask 1 and place five mL of the 3% (undiluted) H2O2 solution and 10 mL of the undiluted IKI solution provided into the flask. Immediately replace the stopper on the flask.Note: At this point, you should select an extra beaker (any volume) from your lab kit to use as an supplemental collection container beaker for Step 6. You do not need to use the beaker yet, but keep it in close proximity.2. Swirl Flask 1 until you observe a steady dripping of water going into the 10 mL graduated cylinder.Figure 2: Apparatus set-up. Note this is a sample set-up and is not drawn to scale. Your specific equipment may vary slightly.Reaction RatesThis could take 3 – 5 minutes. Check for leaks in the tubing or system if water does not start rising up the plastic tubing coming from Flask 2 and traveling towards the graduated cylinder within one minute.3. Stop swirling Flask 1 when you notice the steady flow of water droplets. When you stop, the water drop -rate will significantly decrease (to around one drop every 5 – 20 seconds) and could take a few minutes to stabilize. If a steady flow of drops of water does not occur within a few minutes, swirl Flask 1 for one more minute and check again. Repeat this process until there is a steady flow of drops of wa- ter after you have stopped swirling Flask 1.4. Quickly empty liquid that has collected in the 10 mL graduated cylinder and replace the empty cylinder back under the flexible tubing.5. Allow the flow of drops to become steady again. This could take 1 – 3 mL of water.6. Start timing once the drop rate is steady and the volume of water collected is at a whole number (suchas three mL). Record the time in Table 1 each time 2 mL of is water displaced. Continue taking data until you have at least 10 data points (20 mL displaced).Note: Use the extra beaker (located in Part B: Step 1) to collect additional fluid when the volume ofdisplaced water exceeds 10 mL.7. Return the collected water from your 10 mL graduated cylinder to Flask 2. Ensure the seal is air tight.8. Empty, clean and dry Flask 1 and the graduated cylinder9. Repeat Steps 1 – 8 for the following trial conditions: 5 mL 3% (undiluted) H2O2 mixed with 10 mL of0.5%-1.0% IKI solution (placed in Flask 1); and, 5 mL of 2.25% H2O2 mixed with 10 mL of 1.0%-2.0% IKI solution (placed in Flask 1). Record the data in Table 2 and Table 3, respectively.Note: Clean the graduated cylinder and extra collection beaker before it is used to measure any additional reagents for Trial 2 or Trial 3; and, before it is used for collecting the water from the reac- tion in the apparatus.10. Use a graphing software program to make a graph of each trial. The graph should demonstrate the re- lationship formed between time vs. mL of water displaced.11. Find and record the slope and the inverse slope for each trial.CalculationsReaction RatesTable 1: 10 mL Undiluted (1.0 – 2.0%) IKI and 5 mL 3% H2O2 Table 2: 10 mL 0.5-1.0% IKI and 5 mL 3% H2O2mL water displaced Time (seconds)2____________________________________________________?_________________________________4_____________________________________________________?_________________________________6_____________________________________________________?_________________________________8_____________________________________________________?_________________________________10____________________________________________________?__________________________________12____________________________________________________?__________________________________14____________________________________________________?__________________________________16____________________________________________________?__________________________________18____________________________________________________?__________________________________20____________________________________________________?__________________________________22____________________________________________________?__________________________________Slope: ?Inverse Slope: ?Table 2: 10 mL 0.5-1.0% IKI and 5 mL 3% H2O2mL water displaced Time (seconds)2________________________________________________________?______________________________4________________________________________________________?______________________________6________________________________________________________?______________________________8________________________________________________________?______________________________10_______________________________________________________?_______________________________12_______________________________________________________?_______________________________14_______________________________________________________?_______________________________16_______________________________________________________?_______________________________18_______________________________________________________?_______________________________20_______________________________________________________?_______________________________22_______________________________________________________?_______________________________Slope: ?Inverse Slope: ?Table 3: 10 mL Undiluted (1.0 – 2.0%) IKI and 5 mL 2.25% H2O2mL water displaced Time (seconds)2______________________________________________________?________________________________4______________________________________________________?________________________________6_______________________________________________________?_______________________________8_______________________________________________________?_______________________________10_____________________________________________________?_________________________________12______________________________________________________?________________________________14_______________________________________________________?_______________________________16______________________________________________________?________________________________18_____________________________________________________?_________________________________20_____________________________________________________?_________________________________22______________________________________________________?________________________________Slope: ?Inverse Slope: ?Post-Lab QuestionsReaction Rates1.
