Question
According to Raoult's law, which statement is false?Group of answer choicesThe vapor pressure of a solvent over a solution is less than that of pure solvent.The vapor pressure of a solvent over a solution decreases as its mole fraction increases.The greater the pressure of a gas over a solution the greater its solubility.Ionic solutes dissociate in solution causing an enhancement of all colligative propertiesThe solubility of a gas increases as the temperature decreases.
Solution
The false statement according to Raoult's law is: "The vapor pressure of a solvent over a solution decreases as its mole fraction increases."
According to Raoult's law, the vapor pressure of a solvent over a solution is directly proportional to its mole fraction. This means that as the mole fraction of the solvent increases, the vapor pressure of the solvent over the solution also increases, not decreases.
