The Van der Waal's equation of state for a (slightly) non-ideal classical gas is usually derived in the context of classical statistical mechanics by using the canonical ensemble. We use the hard sphere potential with no short range interaction and derive Van der Waal's equation of state in microcanonical ensemble formulation.
