ResumoAbstract The Benedict‐Webb‐Rubin Equation of State has been generalized by expressing the eight constants as functions of critical pressure, critical temperature, and acentric factor. An evaluation of the resulting generalization against the observed P‐V‐T data of thirteen hydrocarbons and carbon dioxide shows 0.3 to 2.0% average deviations of the calculated pressures from the observed, as compared with 0.2 to 1.4% when using the individual (that is, nongeneralized constants for each component). Standard errors of estimate for 1,464 experimental data points were 0.0089 for the proposed generalization vs. 0.0084 for the original B‐W‐R Equation.
