Which one of the following statements is false ?

Options

A. Raoult’s law states that the vapour pressure of a component 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 `BaCl_(2)gt KClgtCH_(3)COOHgt` sucrose
D. The osmotic pressure `(pi)=` MRT, where M is the molarity of the solution

Explanation

To determine which statement is false, we will analyze each statement one by one based on the principles of solutions and colligative properties.

### Step 1: Analyze Statement 1
**Statement:** Raoult's law states that the vapor pressure of a component of a solution is proportional to its mole fraction.

**Analysis:** According to Raoult's law, the partial vapor pressure of a component in a solution is indeed proportional to its mole fraction in the solution. This is mathematically expressed as:
\[ P = x \cdot P_0 \]
where \( P \) is the vapor pressure of the component in the solution, \( x \) is the mole fraction of the component, and \( P_0 \) is the vapor pressure of the pure component.
