An equation of state based on the intermolecular potential and the radial distribution function to estimate the virial coefficients by using PvT chaotic data

•Approximate radial distribution function using the Ornstein-Zernike equation.•General equation of state which allows analyzing any intermolecular potential.•Thermodynamic model with chaotic behavior and stabilized temperature.•Estimation of virial coefficients through chaotic PvT oscillations.•Very good agreement between the simulated values and the experimental ones.
