Is it true that equations of state for non-ideal gases are complex because intermolecular forces and molecular volumes vary unpredictably?

Yes. Equations of state for non-ideal gases are indeed complex because they must account for varying intermolecular forces and molecular volumes.

The analysis

The retrieved literature consistently supports the claim that non-ideal gas equations of state are complex precisely because they must model varying intermolecular forces (attractions and repulsions) and molecular volumes (such as volume exclusion or effective molar volumes). Papers [0], [2], and [11] explicitly address these factors in real gas dynamics and thermodynamic state equations.
