Unformatted text preview: 1 Wednesday, October 6, 2010 Office Hours: Brian: Th (12:30-1:30) Homework due Friday Chapter 8: Learning Objectives Read the book Air is bubbled through a tank of water at 25 o C and atmospheric pressure. The solubility of O 2 in water is about 0.005 mol% at 25 o C. Estimate the fugacity of oxygen in the water. A. 1 bar B. 0.2 bar C. 0.5 bar D. 2 bar E. 0.0005 bar 0.005 mol/L 0.10 mol/L One component exists in two phases at the same temperature, but the phases are not in equilibrium. What is the direction of mass transfer? A. From α to β. B. From β to α. C. No mass transfer occurs. D. Cannot predict direction. α phase ᵦ phase gas f A liq = 0.6 atm Liquid f A gas = 0.4 atm System is not at Equilibrium Mass transfer of A At equilibrium f A liq = f A gas Liquid water is in VLE at 1.2 atm with water vapor and air in a piston/cylinder. You remove half the air through a selective membrane that does not allow any water to leave. You keep P and T constant....
