ChBE 3110, Fall Semester, 2009 Chemical Engineering Thermodynamics II Problem Set Eight 1. A liquid hydrocarbon A has a saturation pressure of 13.3 kPa at 10 o C. Its density at 25 o C is 0.80 g cm -3 and its molecular weight is 160. This is all the information available on pure liquid A. An equimolar mixture of A in carbon disulfide at 10 o C gives an equilibrium partial pressure of A equal to 8 kPa. Estimate the composition of the vapor that at 10 o C is in equilibrium with an equimolar liquid solution of A in toluene, using the following data: Carbon disulfide Toluene Solubility parameters at 25 o C (J cm -3 ) 1/2 20.5 18.2 Liquid mmolar volumes at 25 o C (cm 3 mol -1 ) 61 107 Saturation pressures at 10 o C (kPa) 1.73 25.5 2. A binary liquid mixture contains nonpolar components 1 and 2. The mixture is to be separated by ordinary distillation. To determine if this is feasible, it is necessary to know whether the mixture has an azeotrope. At 300 K the pure- component vapor pressures are 1 2 53.3 and 80 S S P P kPa . The pure-component

    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.
