Which of the following statements is false?
(i) Two different solutions of sucrose of same molality prepared in different
P solvents will have the same depression in freezing point.
W
(ii) The osmotic pressure of a solution is given by the equation \( \Pi=\mathrm{CR} T \) ( where \( \mathrm{C} \) is the molarity of the solution).
(iii) Decreasing order of osmotic pressure for \( 0.01 \mathrm{M} \) aqueous solutions of barium chloride, potassium chloride, acetic acid and sucrose is
\[
\mathrm{BaCl}_{2}\mathrm{KCl}\mathrm{CH}_{3} \mathrm{COOH}\text { sucrose. }
\]
(iv) According to Raoult's law, the vapour pressure exerted by a volatile component of a solution is directly proportional to its mole fraction in the solution.
