Vedclass · Answer

(D) $1$. Raoult's law states that the partial vapor pressure of each component in a solution is directly proportional to its mole fraction in the solution. This is correct.$2$. The osmotic pressure formula is $\pi = MRT$,where $M$ is the molarity. This is correct.$3$. Osmotic pressure is a colligative property depending on the van't Hoff factor $(i)$. For $0.01 \ M$ solutions: $BaCl_2$ $(i=3)$,$KCl$ $(i=2)$,$CH_3COOH$ $(i \approx 1)$,and sucrose $(i=1)$. The order $BaCl_2 > KCl > CH_3COOH > 	ext{sucrose}$ is correct.$4$. Depression in freezing point $(\Delta T_f = K_f \cdot m)$ depends on the cryoscopic constant $(K_f)$ of the solvent. Since $K_f$ is a characteristic property of the solvent,different solvents will have different $K_f$ values,leading to different depressions in freezing point even if the molality $(m)$ is the same. Thus,statement $D$ is incorrect.
