The following graph shows the relationship between temperature and pressure for 1.0 mol
samples of Ar(g) and Kr(g) confined in separate 1.0 L containers. Ideal behavior under these
conditions is indicated by a dashed line.
Pressure (atm)

150
200
Ar
250 300
Temperature (K)
Kr
350 400

Which of the following best explains why the Kr(g) sample deviates more from ideal behavior
at 200 K than the Ar(g) sample does?
