Which Statement About the Vapor Pressure of a Liquid Is

question 36

Multiple Choice

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.
