Consider a binary solution of two volatile liquid components 1 and 2 x1 and y1 are the mole fractions of component 1 in liquid and vapour phase, respectively. The slope and intercept of the linear plot of \(\frac{1}{\mathrm{x}_{1}} \mathrm{vs} \frac{1}{\mathrm{y}_{1}}\) are given respectively as :
1
\(\frac{\mathrm{P}_{1}^{0}}{\mathrm{P}_{2}^{0}}, \frac{\mathrm{P}_{2}^{0}-\mathrm{P}_{1}^{0}}{\mathrm{P}_{2}^{0}}\)
2
\(\frac{\mathrm{P}_{2}^{0}}{\mathrm{P}_{1}^{0}}, \frac{\mathrm{P}_{1}^{0}-\mathrm{P}_{2}^{0}}{\mathrm{P}_{2}^{0}}\)
3
\(\frac{\mathrm{P}_{1}^{0}}{\mathrm{P}_{2}^{0}}, \frac{\mathrm{P}_{1}^{0}-\mathrm{P}_{2}^{0}}{\mathrm{P}_{2}^{0}}\)
4
\(\frac{\mathrm{P}_{2}^{0}}{\mathrm{P}_{1}^{0}}, \frac{\mathrm{P}_{2}^{0}-\mathrm{P}_{1}^{0}}{\mathrm{P}_{2}^{0}}\)
