For a real gas (van der Waal's gas), behaving ideally, the pressure may be
Options:(select one or more)
Answer:
C
Solution:
Ideal behaviour (Z = 1 at low pressure) requires the second virial coefficient B = b − a/RT to vanish, i.e. RT = a/b. Then P = RT/Vm = a/(bVm), which is option (c); it is also the only dimensionally consistent option (a/(bVm) has units of pressure). Hence (c).
