A) The correct order of osmotic pressure for 0.01 M aqueous solution of each compound is \[BaC{{l}_{2}}>KCl>C{{H}_{3}}COOH>Sucrose\]
B) The osmotic pressure \[\left( \pi \right)\] of a solution is given by the equation \[\pi =MRT\], where M is the molarity of the solution
C) Raoult's law states that the vapour pressure of a component over a solution is proportional to its mole fraction
D) Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depression
Correct Answer: D
Solution :
[d] \[\Delta {{T}_{f}}={{K}_{f}}\times m\times i.\] Since \[{{K}_{f}}\] has different values or different solvents, hence even if m is the same \[\Delta {{T}_{f}}\] will be different
