The vapour pressure of pure liquids p and q
WebMay 27, 2024 · In addition, the fact that the boiling points of the pure compounds differ by more than 3 °C makes the differences between the compositions of the liquid and vapor phases close to zero. The UNIFAC model also predicts the ideal behavior of the liquid phase, but with lower activity coefficients than those estimated using COSMO-RS. WebApr 19, 2024 · For each component we can write that the vapour pressure (related by Dalton's law to the total pressure) is equal to the product of the mole fraction in the solution and the vapour pressure of the pure component: You can exploit the fact that the molar amounts in the problem are particularly tidy: y 1 = n 1 g χ 1 = n 1 l → n 1 g P S = n 1 l ...
