Which of the following statements is false? (A) Two different solutions of sucrose of same molality prepared in different solvents will have the same depression in freezing point (B) The osmotic pressure of a solution is given by the equation π = CRT (where C is the molarity of the solution) (C) Decreasing order of osmotic pressure for 0.01 M aqueous solutions of barium chloride, potassium chloride, acetic acid and sucrose is BaCl2 > KCl > CH3COOH > sucrose (D) According to Raoult’s law, the vapour pressure exerted by a volatile component of a solution is directly proportional to its mole fraction in the solution

The value of Kf depends upon the nature of the solvent. Thus, two different solutions of sucrose of same molality prepared in different solvents will have the different depression in freezing point.

Q. Which of the following statements is false?

Two different solutions of sucrose of same molality prepared in different solvents will have the same depression in freezing point

The osmotic pressure of a solution is given by the equation $π = CRT$ (where $C$ is the molarity of the solution)

Decreasing order of osmotic pressure for $0.01 M$ aqueous solutions of barium chloride, potassium chloride, acetic acid and sucrose is $B a C l_{2} > K Cl > C H_{3} COO H >$ sucrose

According to Raoult’s law, the vapour pressure exerted by a volatile component of a solution is directly proportional to its mole fraction in the solution

The value of $K_{f}$ depends upon the nature of the solvent. Thus, two different solutions of sucrose of same molality prepared in different solvents will have the different depression in freezing point.
