CHEMICAL ENGINEERING THERMODYNAMICS COURSE NO.: CHEG301 STUDENT: ___________________ COURSE: Thermodynamics INSTRUCTOR: Prof. Anderson SUBJECT: Problem Set 14 DUE: Wednesday, Dec. 5, 2007 1. At 20 ° C the solubility of phenanthrene is acetic acid is 0.0192 mole fraction. Estimate the activity coefficient for phenanthrene at this composition. The melting point of phenanthrene is 96.3 ° C and its heat of fusion at its normal melting point is 4456 cal/mol. 2. One hundred moles of a mixture consisting of 15 mole percent 1,4-dioxane, 45 mole percent water, and 40 mole percent benzene is allowed to separate into two liquid phases at 40 ° C. Benzene and water are essentially insoluble in each other. Making appropriate assumptions, estimate the amounts and compositions of the two liquid phases which are formed. Van Laar parameters have been reported for each of the soluble binaries at 40 ° C and are given below: System A 12 A 21 Benzene(1)-1,4-Dioxane(2) 0.0535 0.3055 Water(1)–1,4-Dioxane(2) 1.9459 1.7390 3. The dissociation pressure of calcium oxalate in the reaction CaC O (s)
