Which statement about the vapor pressure of a liquid is not correct?
A)The vapor pressure increases with increasing temperature because more molecules have sufficient energy to overcome the attractive forces that hold them in the liquid.
B)The vapor pressure decreases with increasing strength of intermolecular interactions.
C)The pressure at which the rate of molecules evaporating equals the rate of molecules condensing is called the vapor pressure.
D)Adding a nonvolatile solute to a liquid increases the vapor pressure.
E)The enthalpy of vaporization determines how sensitive the vapor pressure of a substance is to a change in temperature.

Question

Quizplus · Accepted Answer

Adding a nonvolatile solute to a liquid decreases its vapor pressure, according to Raoult's law. This is because the solute molecules occupy space at the surface of the liquid, decreasing the number of solvent molecules that can evaporate and contribute to the vapor pressure.
