Chapter 13, Problem 13.18

(choose chapter or problem)

A liquid mixture of cyclohexanone(1)/phenol(2) for which \(x_{1}=0.6\) is in equilibrium with its vapor at \(144^{\circ} \mathrm{C}\). Determine the equilibrium pressure P and vapor composition \(y_{1}\) from the following information:

∙ \(\ln \gamma_{1}=A x_{2}^{2} \quad \ln \gamma_{2}=A x_{1}^{2}\)

∙ \(\text { At } 144^{\circ} \mathrm{C}, P_{1}^{\text {sat }}=75.20 \mathrm{kPa} \text { and } P_{2}^{\text {sat }}=31.66 \mathrm{kPa}\)

∙ The system forms an azeotrope at \(144^{\circ} \mathrm{C}\) for which \(x_{1}^{\mathrm{az}}=y_{1}^{\mathrm{az}}=0.294\)
