Unformatted text preview: Recitation 10.213 04/29//02 Spring 2002 YT 1) Pxy diagram for a binary mixture (1) and (2) at T = 300 K is given below. a) Identify the three regions. b) Which component has a higher P sat ? Determine P 1 sat and P 2 sat . c) We put a 50-50 mixture of components 1 and 2 in a vessel. We seal the vessel and bring it to 300 K and 1 atm. Describe the content of the vessel. d) What are γ 1 and γ 2 at x 1 = 0.5? The vapor phase can be assumed to be ideal. e) Calculate G E /RT at x 1 = 0.5. 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 0.0 0.2 0.4 0.6 0.8 1.0 x 1 , y 1 P (atm) P T L x 1 , x 2 V y 1 , y 2 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 0.0 0.2 0.4 0.6 0.8 1.0 x 1, y1 P (atm) 1) predict 2) predict Accuracy of prediction depends on experiment Pxy data fit with model eqns G E /RT = f(x 1 , x 2 , T) vs x 1 vs x 1 2) A liquid mixture of toluene and polystyrene (PS) is placed in a vessel. At 300 o C and 25 bar, the liquid solution is in equilibrium with toluene vapor. PS is very involatile, allowing us to assume that there is nosolution is in equilibrium with toluene vapor....
