1. The normal boiling point for acetone is 56.5°C. At an elevation of 5300 feet, the atmospheric
pressure is 630. torr.
a. What would be the boiling point of acetone (AHºvap = 32.0 kJ/mol) at this elevation?

2. Multiple choice...Choose the best answer
At a given temperature, the vapor pressure of SiF4 is significantly higher than that of SF4. The major
physical basis for the difference in vapor pressure is that SiF4 and SF4 have different
(a) dipole moments (b) molar masses (c) ionization energies (d) magnetic susceptibilites

3. Multiple choice...Choose the best answer
The vapor pressure of a liquid increases with an increase in temperature. Which one of the
following statements best explains this increase?
a. The average kinetic energy of molecules is greater, thus more molecules can enter the
gaseous state.
b. The number of gaseous molecules above the liquid remains constant, but these molecules
have greater average kinetic energy.
c. The faster-moving molecules in the liquid exert a greater pressure.
d. All the molecules have greater kinetic energies.
e. The intermolecular forces between the molecules decrease at higher temperatures.
4. The heats of vaporization for water and carbon disulfide are 40.7 kJ/mol and 26.8 kJ/mol,
respectively.
a. Why is the heat of vaporization of water greater than that of carbon disulfide?
