2. Using the reaction mixture in Problem 1, a student found that it took 510 seconds for the color of the 1₂ to disappear. a. What was the rate of the reaction? Hint: First find the initial concentration of I₂ in the reaction mix- ture, [1₂]o. Then use Equation 5. rate= rate = M/sec b. Given the rate from Part (a), and the initial concentrations of acetone, H* ion, and I₂ in the reaction mixture, write Equation 3 as it would apply to the mixture.

1. In a reaction involving the iodination of acetone, the following volumes were used to make up the reac- tion mixture: a. How many moles of acetone were in the reaction mixture? Recall that, for a component A, moles A = MAX V, where MA is the molarity of A and V is the volume in liters of the solution of A that was used. 5 mL 4.0 M acetone + 10 mL 1.0 M HCl + 10 mL 0.0050 M I₂ + 25 mL H₂O M₁ = 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, moles of A V of soln. in liters moles acetone c. 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 I₂ as in the original mixture? rate = 2. Using the reaction mixture in Problem 1, a student found that it took 510 seconds for the color of the 1₂ to disappear. M acetone a. What was the rate of the reaction? Hint: First find the initial concentration of I₂ in the reaction mix- ture, [1₂]o. Then use Equation 5. rate = C. What are the unknowns that remain in the equation in Part (b)? b.
