Estimation of standard heats of formation ΔH, standard entropies of formation ΔS, standard free energies of formation ΔF and absolute entropies S of hydrocarbons from group contributions: An accurate approach

Abstract

Abstract A group contribution method for calculation of standard heats of formation ΔH* fT , standard entropies of formation ΔS* fT standard free energies of formation ΔF* fT and absolute entropies S* T , of hydrocarbons is proposed. It is shown that this method is more accurate than any of the ones now appearing in the literature.
