1. 2. 3. Example: Bubble- and Dew-point Calculations Calculate the temperature and composition of a vapor in equilibrium with a liquid that is 40.0 mol% benzene-60.0 mole% toluene at 1 atm. Total pressure is 760 mmHg. Is the calculated temperature a bubble point or dew point. Calculate the temperature and composition of a liquid in equilibrium with a gas mixture containing 10.0 mol% benzene, 10.0 mole% toluene and the balance is nitrogen (which may be considered noncondensable) at 1 atm. Is the calculated temperature a bubble point or dew point. A gas mixture consisting 15.0 mol% benzene, 10.0 mole% toluene and 75 mole % nitrogen is compressed isothermally at 80°C until condensation occurs. At what pressure will condensation begin. What will be the composition of the initial condensate?
