Gibbs–Helmholtz equation : ウィキペディア英語版 | Gibbs–Helmholtz equation The Gibbs–Helmholtz equation is a thermodynamic equation used for calculating changes in the Gibbs energy of a system as a function of temperature. It is named after Josiah Willard Gibbs and Hermann von Helmholtz. ==Equation==
The equation is:〔Physical chemistry, P.W. Atkins, Oxford University Press, 1978, ISBN 0-19-855148-7〕 where ''H'' is the enthalpy, ''T'' the absolute temperature and ''G'' the Gibbs free energy of the system, all at constant pressure ''p''. The equation states that the change in the ''G/T'' ratio at constant pressure as a result of an infinitesimally small change in temperature is a factor ''H/T''2..
