Question

Verified Solution • 2025–26 Session moderate

Which one of the following statements is false?

A Raoult’s law states that the vapour pressure of a components over a solution is proportional to its mole fraction
B Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depression
C The correct order of osmotic pressure for 0.01 M aqueous solution of each compound is BaCl2 > KCl > CH3COOH > sucrose
D The osmotic pressure (π) = MRT, where M is the molarity of the solution

Accepted Answer

Δ 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

Δ T_{f}

will be different
