surface excess Gibbs energy

https://doi.org/10.1351/goldbook.S06176
Defined by Gσ=HσT Sσ=Aσγ As where Hσ is the
surface excess enthalpy
, T is the
thermodynamic temperature
, Sσ is the
surface excess entropy
, Aσ is the
surface excess Helmholtz energy
, γ is the
surface tension
, and As is the area relative to a
Gibbs surface
.
