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 = 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 `BaCl_(2)gt KCl gt CH_(3)COOH gt` 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.
