1 Problem Set 7 Chem 3900: Physical Chemistry II Spring 2009 Due: Class, Monday, March 30th Please make sure to write your name and the recitation you’ll attend. When you print out your work, try to minimize the number of pages. Feel free to use Mathematica to solve these problems. Problem 1. Consider a mixture of the two volatile liquids CS 2 (component A) and benzene (component B). At T = 25ºC, the vapor pressures of the pure liquids are p A * = 360.924 Torr, p B * = 95.137 Torr. (In this problem we use Torr as the unit of pressure; recall 760 Torr = 1 bar.) (a) Assuming ideal solution behavior, calculate the constant temperature pressure/composition diagram for the mixture at T = 25 ºC. That is, Plot the total vapor pressure of the solution as a function of both liquid and vapor composition (mole fraction of component A). Also calculate and plot the partial pressures p A and p B as a function of liquid and vapor composition. (b) Compare your ideal solution predictions for the total vapor pressure of the solution with the experimental data given in the file solution_1.nb by plotting the data on the same graph. What

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
