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 (π) = MRT, where M is the molarity of the solution

B.

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

(a)p_A = X_A p_A^o : true
(b) ΔTf =Kfm
Kf is dependent on solvent
Thus is dependent on solvent
Thus freezing points [= t(solvent)- ΔT_f) are different.
(c) i = [1 + (y-1) x]
 y = number of ions
x = degree of ionisation
i = 3 for BaCl₂ x = 1 (strong electrolyte)
i = 2 for KCl x = 1 (strong electrolyte)
i = (1+x) for CH₃COOH x<i = (for BaCl₂)>KCl>CH₃COOH>Sucrose
(d)  π = imRT =  = MRT ; true (if van't Hoff factor i = 1
