Which one of the following statements is false?

Options

  1. AThe correct order of osmotic pressure for 0.01 M aqueous solution of each compound is BaCl ₂> KCl > CH ₃ COOH
  2. BThe osmotic pressure ( ) of a solution is given by the equation = MRT , where M is the molarity of the solutio
  3. CRaoult's law states that the vapour pressure of a component over a solution is proportional to its mole fracti
  4. DTwo sucrose solutions of same molality prepared in different solvents will have the same freezing point depres

Correct answer

D. Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depres

Step-by-step solution

T _ f = K _ f m i . Since K _ f has different values for different solvents, hence even if the m is the same T _ f will be different.
