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 need to analyze each of the provided statements regarding solutions and colligative properties.

### Step-by-Step Solution:

1. **Understanding Raoult's Law**:
- **Statement 1**: "Raoult's law states that vapor pressure component over a solution is proportional to its mole fraction."
- According to Raoult's law, the vapor pressure of a component in a solution is indeed proportional to its mole fraction in the solution. This statement is true.
