Schreckenbach Practice problems –6– Some practice problems from Atkins/ de Paula, 8 th edition: Phase diagrams etc.: Discussion questions D6.2, D6.3a, D6.4b Exercises E6.6, E6.7, E6.8, E6.10, E6.13, E6.14a Some practice problems from Atkins/ de Paula, 7 th edition: Phase diagrams etc.: Discussion questions D8.1b, D8.2a – part a, D8.2b – part b Exercises E8.9 , E8.10, E8.11, E8.13, E8.16, E8.17a More practice problems from Laidler/ Meiser (Problems adapted from Laidler Meiser Sanctuary, Physical Chemistry, 4 th ed., Houghton Mifflin) Phase diagrams: Clapeyron and Clausius-Clapeyron equations 58. The molar entropy of vaporization of water is 108.72 J K-1 at 760 Torr. The corresponding densities of liquid water and water vapor are 0.958 kg L-1 and 5.98 * 10-4 kg L-1 , respectively. Calculate the change of pressure for a one-degree change in temperature. (You will have to use the molar mass of water.) 59. Calculate the heat of vaporization of water at 373.15 K and 101.325 kPa using the Clausius-
