Explain elevation of boiling point
WebFeb 13, 2024 · The boiling point elevation resulting from a mixture is a factor of the molal boiling point constant, so the boiling point of a mixture will continue to rise as more of the solute is added to the mixture. This results from the reduction of the solvent's vapor pressure as its molecules are trapped by the solute. There are practical limits to ... WebAug 22, 2015 · The depression of freezing point and elevation of boiling point are, as has been described by @phillip, due to entropic effects. The basic idea can be seen in the change in free energy with temperature as shown below. The phase change occurs where two solid lines cross.
