CHEMICAL ENGINEERING THERMODYNAMICS COURSE NO.: CHEG301 STUDENT: ___________________ COURSE: Thermodynamics INSTRUCTOR: Prof. Anderson SUBJECT: Problem Set 09 DUE: Wednesday, Oct. 24, 2007 1. An insulated tank with total volume of 3 ft 3 , is divided into two sections by a partition. One section is 2 ft 3 and initially contains hydrogen gas at 30 psia and 110 ° F. The remaining section initially holds nitrogen gas at 50 psia and 50 ° F. The adiabatic partition is then removed, and the gases are allowed to mix. Determine the temperature of the equilibrium mixture, the pressure of the mixture, and the entropy change for the process. You can assume that these gases behave ideally. (assume = 5 Btu/lbmol- ° F) ig V C 2. Prove that the fugacity of a mixture is given by: f = f y m i i y i N i F H G I K J = ± 1 Calculate the fugacity of an equimolar mixture of N 2 and CO 2 at 150 atm and 350K. At these conditions in the mixture: ± . ϕ N 2 095 = and ± . CO 2 048 = 3. Oil reservoirs below ground frequently are in contact with underground water and, in
