The concept of the nearest neighboring molecules or coordination number is proposed to be a function of temperature and volume, whereas it is a constant in the original. The dilute gas and hard sphere limits of molecules are employed to determine this function. Improvement of this modification is demonstrated by property calculations for Lennard-Jones fluid. Results of the modified LJD equation of state offer senior accord with simulation data of Lennard-Jones fluid than those of the original version.     UR - https://www.ijche.com/article_15183.html L1 - https://www.ijche.com/article_15183_3663f12b91bc3310a82f2009be828fcf.pdf ER -
