Ecuación de estado cúbica para un fluido simple

Abstract

In this work, a method to build the Cubic Equation of State of a pure substance is presented. The Equation of State is determined with the values of the pressure $P$, the molar volume $v$, and the temperature $T$ in two states, namely, the critical point and the saturated vapor at temperature $T / T_{c} = 0.7$ (where $T_{c} $ is the critical temperature). The resulting Equation is unique for each substance and, in general, different to other known Cubic Equation of State in the literature.
