The effects of the simple composition‐dependent combining rules (conventional, Adachi‐Sugie and van Laar‐Stryjek‐Vera‐type) and Huron‐Vidal‐NRTL mixing rules and different cubic equations of state (Redlich‐Kwong, Soave‐Redlich‐Kwong, Peng‐Robinson and Peng‐Robinson‐Stryjek‐Vera) on excess molar volume correlation are examined. The results obtained for some asymmetric non‐ideal mixtures indicate very good agreement between correlated and experimental data in all cases when Huron‐Vidal‐NRTL mixing rules are coupled with the Peng‐Robinson‐Stryjek‐Vera equation of state.
