CHEMICAL ENGINEERING THERMODYNAMICS COURSE NO.: CHEG5301 STUDENT: ___________________ COURSE: Thermodynamics INSTRUCTOR: Prof. Anderson SUBJECT: Problem Set 11 DUE: Wednesday, Nov. 5, 2008 1. Given the following empirical expression for the molar density of a binary mixture: ρ=+ +++aaxax011212313…find the corresponding expressions for Vand 1V. 22. For the system of acetone(1) and n-hexane(2) at 20°C, the following data are available: GRTxxxxE=+121744818012..bgPsat124 20=.kPaaPsat21595=PAt 20°C calculate the total pressure and vapor composition which would be in equilibrium with liquid mixtures at each of the following compositions: x1= 0.10, x1= 0.63, & x1= 0.90. Assume that the vapor phase behaves ideally. Based on these calculations, how would you characterize this binary system? 3. In older literature x and y data for binary VLE are sometimes represented by smoothing equations of the form: α12221211=++axbxwhere 12is the relative volatility and the
