Shows positive deviation from Raoult's law

Vedclass · Answer

(C) When a solution shows positive deviation from Raoult's law,the intermolecular forces present are weaker than those present in the pure components. This leads to an increase in the total vapour pressure of the solution compared to the ideal case. Because the vapour pressure is higher,the solution reaches the atmospheric pressure at a lower temperature. Therefore,the azeotropic mixture boils at a temperature lower than either of its pure components. Hence,the correct option is $C$.

An azeotropic solution of two liquids has a boiling point lower than either of them when it:
