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 deperssion in freezing point.
B. The osmotic pressure of a solution is given by the equalition `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, patassium chloride, acetic acid and sucrose is
`" "BaCl_(2) gtKClgt CH_(3)COOHgt` sucrose
D. According to Raoult's law, the vapour pressure exerted by a valatiloe component of a solution is directly proportional to its mole fraction in the solution

Answer

A

Explanation

According todefinition of depression in freezing point
`" "DeltaT_(f)=K_(f)m`
when `K_(1)` = freezing point depression constant, value of `K_(1)` depends upon nature of solvent. This is way although the solution have some molality two different solution of sucrose of same molality prepared in different solvent will have different depression in freezing point.
