What relationship does the vapor pressure of a mixture have to that of a pure liquid?

Question

Quizplus · Accepted Answer

According to Raoult's Law, the vapor pressure of a mixture is proportional to the mole fraction of the liquid. As the amount of solute added to the liquid increases, the mole fraction of the pure solvent decreases and the mole fraction of the solute increases, leading to a decrease in vapor pressure. Therefore, option A is incorrect. Option C is also incorrect because it implies that the liquid has a constant vapor pressure, which is not true since the vapor pressure of a liquid increases with temperature. Option D is also incorrect as temperature plays a crucial role in determining the vapor pressure of a mixture but it is not directly related to it.
