How are the boiling point and freezing point of a solvent affected when a solute is added?
a. both the boiling point and the freezing point decrease.
b. both the boiling point and the freezing point increase.
c. the boiling point increases, and the freezing point decreases.
d. the boiling point decreases, and the freezing point increases.

In dilute solutions, the mole fraction of the solute is proportional to the molality of the solution, as shown in the figure below. The equation that describes the magnitude of the boiling point elevation that occurs when a solute is added to a solvent is therefore often, adding a solute to a solvent will reduce its freezing temperature and increase its boiling temperature.

Idk the answer sorry

Afraidsugar lol it’s the third one
