Unformatted text preview: Chemistry 154.002 Experiment 4 Chemical Kinetics Lauren Best Partner: Glenn Cormack 3/10/08 TA: Lek 1. Objective The purpose of this experiment is to determine the rate law and energy of activation for the oxidation of an iodide ion to elemental iodide by using the method of initial rates at room temperature. 2. Procedure A) 1) Label four 30 mL beakers for thiosulfate, iodide, bromate, and the acid reagents, and fill volumes using Table 1, on pg. 66 in the manual. 2) Gather 12 6-inch test tubes. Dispense the volumes of thiosulfate, iodide, bromated, and acid reagent, using pipets, described in Table 2 on pg. 67 of the lab manual. Label the “A” test tubes: 1A, 2A, 3A, 4A, 3AH, and 3AC. Label the “B” test tubes: 1B, 2B, 3B, 4B, 3BH, and 3BC. B) In this part of the lab, four experiments at room temperature are used to calculate the values on m, n, and p. 1) Add three drops of starch solution to the “B” test tube 2) Pour tube “A” into tube “B” 3) Cap with a rubber stopper and shake vigorously until the solution turns blue. Make sure to 3) Cap with a rubber stopper and shake vigorously until the solution turns blue....
