?A single \(P-x_{1}-y_{1}\) data point is available for a binary system at \(25^{\circ}

Chapter 13, Problem 13.63

(choose chapter or problem)

A single \(P-x_{1}-y_{1}\) data point is available for a binary system at \(25^{\circ} \mathrm{C}\). Estimate from the data:

(a) The total pressure and vapor-phase composition at  \(25^{\circ} \mathrm{C}\) for an equimolar liquid mixture.

(b) Whether azeotropy is likely at  \(25^{\circ} \mathrm{C}\).

Data: \(\text { At } 25^{\circ} \mathrm{C}, P_{1}^{\text {sat }}=183.4 \text { and } P_{2}^{\text {sat }}=96.7 \mathrm{kPa}\)

         \(\text { For } x_{1}=0.253, y_{1}=0.456 \text { and } P=139.1 \mathrm{kPa}\)

At 25^circ C, P_1^sat=183.4 and P_2^sat=96.7kPa

For x_1=0.253, y_1=0.456 and P=139.1 kPa
