SUMMARY
The discussion centers on finding the free energy for nitrogen (N2) and specifically addresses the residual Helmholtz energy (alpha_r) as described in the NIST paper by Roland Span et al. The paper provides a reference equation of state for the thermodynamic properties of nitrogen at various temperatures and pressures. A participant questions the possibility of negative values for alpha_r, citing a calculated value of -0.0017, and seeks clarification on the implications of both positive and negative alpha_r values.
