Which of the following statements is false ?

Options

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 `pi`=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_3COOH gt `surcose.
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

A

Explanation

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.
