We flash distill a mixture that is \(24.1 \mathrm{~mol} \%\) ethane, \(39.7 \mathrm{~mol} \% \mathrm{n}\)-hexane, and \(36.2 \mathrm{~mol} \% \mathrm{n}\)-heptane. If \(\mathrm{p}_{\text {drum }}=101.3 \mathrm{kPa}\) and \(\mathrm{T}_{\text {drum }}=65^{\circ} \mathrm{C}\), find \(\mathrm{V} / \mathrm{F}, \mathrm{y}_{\mathrm{i}}\), and \(\mathrm{x}_{\mathrm{i}}\) values. Use Eq. (2-28).
