Vedclass · Answer

(D) $1$. In an ideal solution,the intermolecular forces between solute-solute,solvent-solvent,and solute-solvent are identical. Thus,the heat of vaporisation remains similar as the same forces are overcome. $2$. The entropy of a solution is higher than that of a pure solvent due to increased disorder. Therefore,the entropy change $(\Delta S)$ between the solution and its vapour is smaller than that between the pure solvent and its vapour. $3$. Due to the presence of a non-volatile solute,the vapour pressure of the solution decreases,which leads to an elevation in the boiling point compared to the pure solvent. $4$. Since all statements are scientifically accurate,the correct option is $D$.

Select the correct statement for an ideal solution of a non-volatile solute in a liquid solvent.
