Which statement explains why an increase in molality increases the boiling point of a solution? the addition of solute decreases the solvent’s vapor pressure. a higher temperature must then be applied to overcome the change. the addition of solute increases the solvent’s vapor pressure. a higher temperature must then be applied to overcome the change. the addition of solute increases the solvent’s ability to boil. the solute’s molecules repel the solvent’s molecules, giving them higher binding energy and hence the need for higher temperature.
