Post Lab Questions: Answer question on this sheet. Show all work. 1. In a reaction involving the iodination of acetone, the following reaction mixture was used 15mL 4.0 M acetone, 15.00 mL. 1.0 M HCl, 15.00 mL. 0.0050 M 12, and 20.0 ml water. a. What was the molarity of the acetone, HCl and I, in the reaction mixture? (Recall that . s ml Hc I2. M- 0.231 b. The color of the above reaction mixture disappeared in 450 seconds. What was the rate of the reaction? (Hint: First determine the initial concentration of the iodine.) rate=-( 4505-0 2. A second reaction mixture was made: 30mL 4.0 M acetone, 15.00 mL 1.0 M HCI, 15.00 mL 0.0050 M I, and 5.0 mL water. -5 mL What was the molarity of the acetone, HCl and I, in this reaction mixture? acetone a. HCl m 1.85 m-1.15 x 1D The iodine color disappeared in 216 seconds. What was the rate of the reaction? rate b. Determine the order of the reaction (m) with respect to acetone using the informati from question 1 and 2. (Round off the value of m to the nearest integer) c. 43
