CHAPTER 4: EXPERIMENTS 156 To = k[H,021 (1) (4.4.11) n А convenient way to determine Tate constant from the measurements is to plot no against [H,021"[). The slope of the plot will be equal to k. Tabulate and plot these values and determine the slope and thereby rate constant, k, using the method of least squares. POST-LAB QUESTIONS 1. Do m and n have to be integers? Why did you round off the numbers you obtained to the nearest integers? 2. What is the order of the overall reaction? 3. Why sulfuric acid (H2SO4), sodium thiosulfate (Na2S203) and water (H20) are added to the reaction medium when the only reaction we are interested in is the one between potassium iodide (KI) and hydrogen peroxide (H2O2)?
