Chemistry - Liquid Solution Question with Solution | TestHub

When an ideal binary solution is in equilibrium with its vapour, molar ratio of the two components in the solution and in the vapour phase may or may not be same depending upon volatile nature of the two components.
Recall that${\mathrm{P}}_{\mathrm{A}}^{\mathrm{\text{'}}}={\mathrm{P}}_{\mathrm{M}}\times {\mathrm{X}}_{{\mathrm{A}}_{\left(\mathrm{i}\mathrm{n }\mathrm{v}\mathrm{a}\mathrm{p}\mathrm{o}\mathrm{u}\mathrm{r }\mathrm{p}\mathrm{h}\mathrm{a}\mathrm{s}\mathrm{e}\right)}}={\mathrm{P}}^0\times {\mathrm{X}}_{{\mathrm{A}}_{\left(\mathrm{i}\mathrm{n }\mathrm{l}\mathrm{i}\mathrm{q}\mathrm{u}\mathrm{i}\mathrm{d }\mathrm{p}\mathrm{h}\mathrm{a}\mathrm{s}\mathrm{e}\right)}}$.
