Question

(B) For a solution to show positive deviation from Raoult's law,the intermolecular forces between the solute and solvent molecules ($A-B$ interaction)

Vedclass · Accepted Answer

$A-B$ interaction is weaker than $A-A$ and $B-B$ interaction

Vedclass · Answer

(B) For a solution to show positive deviation from Raoult's law,the intermolecular forces between the solute and solvent molecules ($A-B$ interaction) must be weaker than the forces between the pure components ($A-A$ and $B-B$ interactions).This results in an increase in the total volume of the mixture $(\Delta V_{mix} > 0)$ and an absorption of heat $(\Delta H_{mix} > 0)$.

In a mixture of $A$ and $B$ components,the solution shows positive deviation from Raoult's law when:
