WebApr 8, 2024 · The quantity termed as “free energy” is an advanced and accurate replacement for the archaic term “affinity”. This term was used by chemists in the initial years of physical chemistry to portray the forces behind chemical reactions. Furthermore, in 1873, Josiah Willard Gibbs published his paper, “A Method of Geometrical … WebMathematically, Gibbs free energy is determined by subtracting the product of temperature and entropy change from the enthalpy change, as presented in Eq. (7.13). (7.13) The …
