6-9-1. A gas occupies a volume of 22.0 L/mol at STP. Which of the
following explains the deviation from ideal behavior?
A. predominance of attractive forces among the molecules
B. predominance of repulsive forces among the molecules
C. absence of attractive forces among the molecules
D. absence of repulsive forces among the molecules
6-9-2. A 2.00 mol sample of gas occupies a volume of 11.0 L at 298K and 5.00 atm. These values suggest that…
A. the gas is behaving ideally
B. the gas is not behaving ideally and the deviation is due to
predominance of attractive forces
C. the gas is not behaving ideally and the deviation is due to
the predominance of repulsive forces
6-9-3. The compression factor for a 2.50 L gas sample is 1.20. If the gas were ideal, at the same temperature and pressure, the volume would be
A. higher than 2.50 L,
B. smaller than 2.50 L,
C. the same,
D. different, but information is insufficient
6-9-4. The compression factor for a gas sample is 0.90; its pressure is 20.0 atm. If the gas were ideal, at the same temperature and volume, the pressure would be
A. higher than 20.0 atm, B. lower than 20.0 atm, C. the same,
D. different, but information is insufficient
