Which of the following statements is false?

MCQ

✓
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 $\pi=\text{CRT}\ ($where $C$ is the molarity of the solution$).$
C
Decreasing order of osmotic pressure for $0.01M$ aqueous solutions of barium chloride, potassium chloride, acetic acid and sucrose is $\mathrm{BaCl}_2 > \mathrm{KCl} > \mathrm{CH}_3 \mathrm{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.

Answer

Correct option: A.

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

$\text{Tf = Kfm}$ Since $Kf$ values depend upon the nature of solvent, the depression in freezing point of the solution would not be the same.
