Vedclass · Answer

(C) For an ideal solution,the intermolecular forces of attraction between $A-A$ and $B-B$ are equal to those between $A-B$. Thus,option $A$ is incorrect.Henry's law relates the solubility of a gas in a liquid to the partial pressure of the gas,not directly to temperature. Thus,option $B$ is incorrect.When a solution shows a negative deviation from Raoult's law,the intermolecular forces between $A$ and $B$ are stronger than those between $A-A$ and $B-B$. This leads to a decrease in vapor pressure and an increase in boiling point,resulting in a maximum boiling point azeotrope. Thus,option $C$ is correct.The addition of a nonvolatile solute to a volatile solvent leads to an elevation in boiling point,not a decrease. Thus,option $D$ is incorrect.
