10:19 1. Prepare two flasks for each experiment (Table RR.1) using the stock solutions (Table RR.2). Remember to include these steps in your notebook. DO NOT CONFUSE the $,0,³" with the 5,0,¹1 Flask #1 Flask #2 Table RR.1: Reaction Concentrations and Volumes for Experiments 1-3 0.1 M EDTA 1% Starch Indicator 0,20 M Na $₂0, 0.20 M KNO, 0.20 M KI 0.20 M (NH₂),S,O, Solution Experiment 1 3 drops 1.0 mL 1.0 ml. KNO, Na S,0, (NH,) S.O. 120 ml 0.20 M 24.0 mL 0.20 M 120 ml. Concentration 0.20 M Table RR.2: Concentrations of Stock Solutions Total Volume 50.0 ml. 50.0 ml. 50.0 ml. EDTA is added to complex out any spurious metals that might act as a catalyst for the reaction and change the overall rate. The peroxydisulfate, iodide and thiosulfate ions are not found alone but as ammonium, potassium and sodium salts, respectively. The KNO, is added to maintain the ionic strength of the solutions. Experiment 2 3 drops 1.0 mL 1.0 mL 24.0 ml. 12.0 mL Solution KI 120 ml. Starch Indicator EDTA .. LTE Experiment 3 3 drops 1.0 mL 1.0 mL 12.0 ml. 0.20 M -0.1 M 12.0 mL 24.0 ml. Concentration

(Opts) What is the slope of your best fit line in the calibration curve? (Opts) What is the y-intercept of your best fit line in the calibration curve?
(1pts) Enter the reaction order (a) you calculated for peroxydisulfate (S₂02)
Table view List view Calculate the initial concentrations on each of the reagents in the three experiments. Values for the first two columns of the following table come from using the dilution formula with data from Table A in the experiment PDF. Values for the final column come from the graphs. Please report your initial rate in scientific notation to 2 significant figures, such as 1.2 x 10^3 Experiment 1 Experiment 2 Experiment 3 [S₂0,²1 011 Initial rate (mol/L's), Report to 2 sig figs
(1pts) Enter the reaction order (b) you calculated for iodide (1)
Rate Constants Calculate the reaction rate constant, k, for each experiment. Be sure to show units. Experiment 1 Experiment 2 Experiment 3 Average Constant Table view List view Rate Constant
