CHEMICAL ENGINEERING THERMODYNAMICS COURSE NO.: CHEG5301 STUDENT: ___________________ COURSE: Thermodynamics INSTRUCTOR: Prof. Anderson SUBJECT: Problem Set 10 DUE: Wednesday, Oct. 29, 2008 1. At -100 ° C, a gaseous mixture of one gram mole contains 1 mol % CO 2 and 99 mol % H 2 . The mixture is compressed isothermally to 60 atm. Does any CO 2 precipitate? If so, approximately how much? (At -100 ° C, the vapor pressure of pure solid CO 2 is 0.1374 atm and the molar volume of solid CO 2 is 27.6 cm 3 /mol.). Second Virial Coefficients, cm 3 /gmol: CO 2 - 1 & H 2 - 2 B 11 = -457.85 B 12 = -25.34 B 22 = 4.77 2. A thin membrane, permeable only to hydrogen, separates two chambers maintained at a constant temperature of 40 ° C. A mixture consisting of 0.1 moles of hydrogen and 0.9 moles of nitrogen at a pressure of 50 atm is contained on one side. Using the virial equation of state, determine the pressure at which pure hydrogen must be maintained in the other chamber. Virial coefficients may be estimated using the correlation of Abbot. Abbott gives the second virial coefficients in terms of the following correlation:
