Components of a binary mixture of two liquids A and B were being separated by distillation. After some time separation of components stopped and composition of vapour phase becomes same as that of liquid phase. Both the components started coming in the distillate. explain why this happened.

Give two examples where fractional distillation is used to separate the components of a mixture

At 20^@C the vapour pressure of pure liquid A is 22 mm Hg and that of pure liquid B is 75mm Hg. What is the composition of the solutions of these two components that has a vapour pressure of 48.5 mm Hg at this temperature?

The liquids X and Y from ideal solution having vapour pressures 200 and 100mm Hg respectively. Calculate the mole fraction of component X in vapour phase in equilibrium with an equimolar solution of the two.

An ideal solution has two components A is more volatile than B, i.e. P_A^(@)gtP_B^(@) and also p_A^(@) gt P_("total") . If X_(A) andY_(A) are mole fraction of components A in liquid and vapour phases, than :

X_(A) and X_(B) are the mole fraction of A and B respectively in liquid phase y_(A) and y_(B) are the mole fraction of A and B respective in vapour phase. Find out the slope of straight line if a graph is plotted (1)/(y_(A)) along Y-axis against (1)/(x_(A)) along X-axis gives straight line [p_(A)^(@) and p_(B)^(@) are vapour pressure of pure components A and B].

Boiling point composition diagram of the liqid-vapour equilibrium for A and B is shown in the figure. If a binary liquid mixture of A and B is distilled fractionally, which of the following would be correct observation ?
