According to Raoult's law, which statement is false
A) The vapor pressure of a solvent over a solution decreases as its mole fraction increases.
B) The solubility of a gas increases as the temperature decreases.
C) The vapor pressure of a solvent over a solution is less than that of a pure solvent.
D) The greater the pressure of a gas over a solution the greater its solubility.
E) Ionic solutes dissociate in solution causing an enhancement of all colligative properties.

Question

Quizplus · Accepted Answer

Raoult's law states that the vapor pressure of a solvent over a solution is directly proportional to its mole fraction in the solution. Therefore, as the mole fraction of the solvent increases, its vapor pressure over the solution also increases, not decreases.
