According to Raoult's law, the statement which is FALSE is:

  • A) The vapor pressure of a solvent over a solution decreases as its mole fraction increases.

Raoult's law states that if the pressure of the content of a liquid remains constant to the temperature, then it is proportional to the mole fraction of the mixture.

As a result of this, the vapor pressure of a solvent over a solution is less than the pure solvent and the greater the pressure of a gas over a solution, the greater the solubility.

Therefore, the correct answer is option A because it is false.
