When a Nonvolatile Solute Is Dissolved in a Volatile Solvent

When a nonvolatile solute is dissolved in a volatile solvent, the vapor pressure, freezing point, and boiling point

A) are all higher for the solution than for the pure solvent.
B) are all lower for the solution than for the pure solvent.
C) change differently, with vapor pressure increasing and boiling and freezing points decreasing.
D) change differently, with boiling point increasing and vapor pressure and freezing point decreasing.
E) do not change because the solute is nonvolatile.
