Which one of the following statement is Flase?

A

Raoult's law states that the vapour pressure of a component over a solution is proportional to its mole fraction

B

The osmotic pressure `(pi)` of a solution is given by the equation `pi = MRT` where `M` is the molarity of the solution

C

The correct order of osmotic pressure for `0.01M` aqueous solution of each compound is `BaCI_(2) gt KCI gt CH_(3)COOH gt` Sucrose

D

Two sucrose solution of same molarity prepared in different solvent will have the same freezing point depression

Text Solution

Verified by Experts

The correct Answer is:
D
Different solvent would have different `K_(f)` hence different `DeltaT_(f)`
`DeltaT_(f) = K_(f) m`
