Which of the following is/are correct for an ideal binary solution of two volatile liquids (eg. benzene & toluene) ?

Its vapor is always richer in the more volatile component (compared to the liquid).

The liquid will gradually become richer in the less volatile component if such a mixture is boiled (distilled).

The PT (ie. the total pressure) above the solution will be the sum of the vapor pressures of the two pure components.

The boiling point of the solution will be less than the boiling points of the two components.
