Advance Study Assignment: The lodination of Acetone 1. In a reaction involving the iodination of acetone, the following volumes were used to make up the reac- tion mixture: 5 mL 4.0 M acetone + 10 mL 1.0M HCI+10 mL 0.0050 M1, + 25 mL H,o How many moles of acetone were in the reaction mixture? Recall that, for a component A, moles A-MA × V, where MA is the molarity of A and V is the volume in liters of the solution of A that was used a. moles acetone b. What was the molarity of acetone in the reaction mixture? The volume of the mixture was 50 mL 0.050 L, and the number of moles of acetone was found in Part (a). Again, A Vof soln. in liters -M acetone How could you double the molarity of the acetone in the reaction mixture, keeping the total volume at 50 mL and keeping the same concentrations of H' ion and l as in the original mixture? c. Double acetone volume to i2, aud H2o to 3omL Using the reaction mixture in Problem 1, a student found that it took 510 seconds for the color of the I2 to disappear. 2. What was the rate of the reaction? Hint: First find the initial concentration of 1, in the reaction mix- ture, lIgh- Then use Equation 5 a. 6 .dolM S/D sees Given the rate from Part (a), and the initial concentrations of acetone, H' ion, and I, in the reaction mixture, write Equation 3 as it would upply to the mixture b. rate e. What are the unknowns that remain in the equation in Part (b)? (continued on following page)
