Unformatted text preview: Chem 125 Dr. Retsek Winter 2008 Experiment 5: The Hydrolysis of Tertiary-Butyl Chloride: A Chemical Kinetic Study Lab Report Due: Beginning of lab during week 6 (week of February 11 th to February 15 th ). This lab is worth 15 points (instead of the usual 10 points). Part 1: pH to [HCl] to [t-BuCl] data 1. Write the balanced chemical reaction below (be sure to include states of matter): 2. Show the calculation for [HCl] t for time = 30 seconds (starting with the pH at 30 seconds) in your room temperature experiment. In the table below, record your results for [t-BuCl] initial at the three different temperatures. Title this table (in the space below) and use units where appropriate. Temperature Actual Temperature [t-BuCl] initial Room Cold Hot 3. Show the calculation for [t-BuCl] t for time = 30 seconds in your room temperature experiment. 4. Complete the following: As the reaction proceeds (circle one): Question Answer A Answer B Chem 125 Dr. Retsek Winter 2008 (a) pH increases decreases (b) [H + ] increases decreases (c) [t-BuCl] increases decreases Attach an Excel graph of pH vs. time for room temperature only.
