  1. Consider separate 1.0-L gaseous samples of H2, Xe, Cl2, and O2 all at STP.
    1. Rank the gases in order of increasing average kinetic energy.
    2. Rank the gases in order of increasing average velocity and explain logic.
  2. How would it be possible for the molecules in a sample of O2 gas to have the same average velocity as the molecules in a sample of H2 gas?
  3. Ammonia molecules can attract each other using relatively strong hydrogen bonds.  Neon atoms can only attract each other by weaker dispersion forces.  Thus, at the same conditions of temperature and pressure, ammonia gas deviates more from ideal than neon gas.  Explain why ammonia gas deviates more from ideal by discussing how pressure or volume is affected by ammonia’s stronger attractions.
  4. Under the same conditions of temperature and pressure, which of the following gases would behave the most ideally with respect to volume: Ne, N2 or CH4? Explain your logic.
