A simple distillation flask (V=2L) is initially charged with 320 moles of a solution consisting of 40 mole % ethanol (A) and 60 mole % water (B). This solution is evaporated at a constant rate of 1.6 moles/min. The vapor is then condensed and collected in separate flask as distillate. Determine mole fraction of ethanol in the distillate when three-fifth (3/5) of the solution is evaporated and condensed. The equilibrium relation between XA (mol fraction of A in liquid phase) and ya (mol fraction of A in vapor phase) is: yA/XA=2

An excess amount of Ba(NO3)2 was added to 2 liters of water at 25 oC until the solution is saturated. Because Ba(NO3)2 is only slightly soluble in water, the excess Ba(NO3)2 was filtered out to get a solid-free mixture. The proponents of the experiment thought about using the concept of colligative properties, specifically boiling point elevation, to determine Ksp. It was observed in their experiments that the solution boils at 100.15 deg C. Kb of water = 0.51 K-kg/mol. Barium nitrate dissociates using: Solve the ff: a) Amount of Ba(NO3)2 dissolved in grams.

Methane (melting point 91 K) and tetrafluoromethane (melting point 89 K) do not form solid solutions with each other, and as liquids they are only partially miscible. The upper critical temperature of the liquid mixture is 94 K at x(CF4) = 0.43 and the eutectic temperature is 84 K at x(CF4) = 0.88. At 86 K, the phase in equilibrium with the tetrafluoromethane-rich solution changes from solid methane to a methane-rich liquid. At that temperature, the two liquid solutions that are in mutual equilibrium have the compositions x(CF4) = 0.10 and x(CF4) = 0.80. Sketch the phase diagram.
