Which of the following binary mixture does not show the behaviour of minimum boiling azeotropes?
Liquid A and B form an ideal solution. The vapour pressures of pure liquids A and B are 350 and 750 mm Hg respectively at the same temperature. If $x_A$ and $x_B$ are the mole fraction of A and B in solution while $y_A$ and $y_B$ are the mole fraction of A and B in vapour phase, then,
Match List - I with List - II.
List - I | List - II |
---|---|
(A) Solution of chloroform and acetone | (I) Minimum boiling azeotrope |
(B) Solution of ethanol and water | (II) Dimerizes |
(C) Solution of benzene and toluene | (III) Maximum boiling azeotrope |
(D) Solution of acetic acid in benzene | (IV) ΔVmix = 0 |
Choose the correct answer from the options given below :
Given below are two statements:
Statement (I) : Molal depression constant $\mathrm{K}_f$ is given by $\frac{\mathrm{M}_1 \mathrm{RT}_f}{\Delta \mathrm{~S}_{\mathrm{fus}}}$, where symbols have their usual meaning.
Statement (II) : $\mathrm{K}_f$ for benzene is less than the $\mathrm{K}_f$ for water.
In the light of the above statements, choose the most appropriate answer from the options given below :
