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 increases with increasing strength of intermolecular interactions because molecules are better able to pull each other into the gas phase.
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 decreases the vapor pressure.
E) The enthalpy of vaporization determines how sensitive the vapor pressure of a substance is to a change in temperature.

The statement "The vapor pressure increases with increasing strength of intermolecular interactions because molecules are better able to pull each other into the gas phase" is incorrect. Intermolecular interactions, such as hydrogen bonding, dipole-dipole forces, and London dispersion forces, actually make it more difficult for the molecules to overcome the attractive forces and enter the gas phase, resulting in a lower vapor pressure.
