Which of the following statements is false?

Difficult

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 (where, C is the molarity of the solution).
C

The osmotic pressure of 0.01 M aqueous solutions of barium chloride, potassium chloride, acetic acid and sucrose is
${BaCl}_{2} > KCl > {CH}_{3} COOH > Sucrose$
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.

Solution

According to definition of depression in freezing point
$Δ T_{f} = K_{f} m$
Where, $K_{f} =$ freezing point depression constant, the value of K_f depends upon nature of solvent. This is why although the solutions have same molality two different solutions of sucrose prepared in different solvents will have different depression in freezing point.
