Step 1
To estimate the temperature where boiling begins for a solution containing 1 mol of each compound at 760 torr, we need to find the point on the phase diagram where the liquid-vapor equilibrium line intersects the 760 torr pressure line and the 0.5 mole fraction Show more…

Hexane and heptane form an ideal solution. When the solution consists of 19 mole % hexane and 81 mole % heptane, its normal boiling point is 90.37°C. At this temperature, the vapor pressure of pure hexane is 190.1 kPa. a) Estimate the partial pressure of hexane in the vapor phase above the boiling liquid mixture, in kPa. b) What is the composition of the vapor phase above the boiling liquid mixture, in mole fraction of hexane and heptane? Assume that the vapor behaves as an ideal gas. c) Estimate the vapor pressure of pure heptane at this temperature, in kPa.

A solution of hexane (CH3(CH2)2CH3) and pentane (CH3(CH2)3CH3) has a mole fraction of pentane of 0.432. Both hexane and pentane are volatile liquids. At 20°C, the vapor pressure of pure hexane is 131 torr and the vapor pressure of pure pentane is 425 torr. Assuming ideal behavior, answer questions (a) and (b) below: a) (4 pts) Determine the total vapor pressure above the solution. b) (2 pts) Determine the mole fraction of pentane in the vapor phase above the solution at 20°C. c) (4 pts) The actual vapor pressure above the solution agrees closely with the ideal vapor pressure, thus the solution is behaving ideally as we assumed. Explain why the solution is behaving ideally. You must be clear and complete to receive full credit.

A phase diagram of temperature versus composition for a mixture of the two volatile liquids hexane (bp $=69^{\circ} \mathrm{C} )$ and decane $\left(\mathrm{bp}=126^{\circ} \mathrm{C}\right)$ is shown. Assume that you begin with a mixture containing 0.60 $\mathrm{mol}$ of decane and 0.40 mol of hexane. (a) What region on the diagram corresponds to vapor, and what region corresponds to liquid? (b) At what approximate temperature will the mixture begin to boil? Mark as point A on the diagram the liquid composition at the boiling point, and mark as point B the vapor composition at the boiling point. (c) Assume that the vapor at point $\mathrm{B}$ condenses and is reboiled. Mark as point $\mathrm{C}$ on the diagram the liquid composition of the condensed vapor and as point $\mathrm{D}$ on the diagram the vapor composition of the reboiled material.
