Which one of the following statements is false?

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

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

The correct order of osmotic pressure for 0.01 M aqueous solution of each compound is BaCl₂ > KCl > CH₃COOH > sucrose

The osmotic pressure ($$\pi$$) = MRT, where M is the molarity of the solution

הֶסבֵּר

$$\Delta {T_f} = {K_f} \times m \times i.$$ Since $${K_f}$$ has different values for different solvents, hence even if the $$m$$ is the same $$\Delta {T_f}$$ will be different
