Benson’s group additivity method is a semi-empirical approach for estimating thermodynamic properties of organic molecules in the gas phase, including enthalpy of formation (ΔHf°), entropy (S°), and heat capacity (Cp°). This paper presents a detailed review of the theoretical foundations, mathematical formalism, application procedures, and limitations of Benson’s method, with emphasis on chemical calculations relevant to reaction engineering and mechanistic chemistry. A step-by-step calculation example is included.

La búsqueda del es el primer paso de un viaje fascinante hacia la termoquímica predictiva. Este documento es mucho más que un archivo; es la herramienta que permite a ingenieros y químicos diseñar reacciones más seguras, predecir la inflamabilidad de combustibles y entender la estabilidad de nuevos materiales. [ \Delta H^0_f = [4 \times (-10
Benson provided group Cp° values as polynomial coefficients: including enthalpy of formation (ΔHf°)
