Statistical complexity, virial expansion, and van der Waals equation

• We specialize the notion of statistical complexity for a real gas.
• We obtain van der Waals isotherms expressed in complexity terms.
• A complexity-like equation of state is obtained.

We investigate the notion of LMC statistical complexity with regards to a real gas and in terms of the second virial coefficient. The ensuing results are applied to the van der Waals equation. Interestingly enough, one finds a complexity-interpretation for the associated phase transition.
