Connected to DESKTOP-VKHKVG3 A solute added to a solvent raises the boiling point of the solution because Molal Boiling-Point Elevation Constants (Kb) and Freezing-Point nts the temperature to cause boiling must be great enough to boil not only the solvent but also the solute. Disconnect the solute particles raise the solvent's vapor pressure, thus requiring a higher temperature to cause boiling. 06:28 / 31:54 "TRU the solute particles lower the solvent's vapor pressure, thus requiring a higher temperature to cause boiling. the solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV = nRT]).
