Theoretical Evaluation of Second Virial Coefficient over Yukawa Potential

In this paper, a new simple, and the easy analytical formula is proposed to calculate the second virial coefficient with Yukawa potential. As it is known, the suggested analytical formula can be used to investigate some thermodynamic properties and predictors for protein crystallization and intermolecular interaction potential of fluids. The formula is tested for gas-liquid critical points and Hard-core Yukawa potential with different interaction ranges. The calculation results have been compared with different methods in literature data and the results agree with the literature data. Note that the second virial coefficient can provide significant results in the evaluated protein crystallization and investigate the gas-liquid separation with critical temperature.
