Question

The van der Waals parameters for several gases are given in Table 7.4. Use those data to answer the following. Rigid vessels with a volume of 2.000 Liter are filled with 50.00 moles of one of the following gases at 362.0 K. Calculate the pressure of each in bar.

(a) an ideal gas (van der Waals parameters are zero)

(b) argon

(c) xenon

For (b) and (c), is the attractive or repulsive portion of the interatomic potential energy dominant under these conditions?
