Chem 125 Winter 2009 Dr. Abel Name: Olivia Nixon Lab Day and Time: Tuesday 8am Partner(s): __________________________ The Hydrolysis of Tertiary-Butyl Chloride: A Chemical Kinetic Study Part 1: From pH to [Cl - ] and to [t-BuCl] data 1. What formula did you use to convert from pH to [Cl - ] data? Show a sample calculation converting pH to [Cl - ] for one of your data points. pH= -log ( H + ) H + = 10 -pH [HCl] = [HCl] t observed – [HCl] 0 [HCl] = 10 -2.91765796661 – 10 -7.73 [HCl] = .00120875 2. What formula did you use to calculate [t-BuCl] initial at room temperature. Show a sample calculation for one of your data points. [BuCl] = [HCl] f – [HCl] t At t = 95 [BuCl] = .00120875 - .0001084 [BuCl] =.00110035 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. Concentration of BuCl at Different Temperatures Temperature Actual Temperature [t-BuCl] i Room Temp 21 °C .00120875 Room + ~5 ° C 26 °C .000216865 Room + ~10 ° C 31 °C .000343287
