Metals and Chemical Change
We define a quantity G in terms of enthalpy and entropy, writing it G = H-TS (ll.l) G
is known variously as the Gibbs function or the Gibbs free energy, after the
American physicist, Josiah Willard Gibbs (Figure ll.l). ^ According to this definition

Physical Chemistry: Understanding our Chemical World
181, we looked at the phase changes of a single-component system (our
examples included the melting of an ice cube) in terms of changes in the molar
Gibbs function Gm. In a similar manner, we now look at changes in the Gibbs
function for ...

Entropies for selected substances are also available from the NIST software and
online database [11]. s, Gibbs Free Energy or Gibbs Function The Gibbs free
energy or Gibbs function, G, is a composite property involving enthalpy and
entropy ...

Note that a similar equation is obtained in terms of the derived property, enthalpy,
by combining Eqs. (2.5) and (2.10) to give Tds = dh-vdp (2.12) 2.10 The Gibbs
Function and the Helmholtz Function Two further derived properties are defined ...

6.5 THE GIBBS FUNCTION G This state function is designed for use in problems
where pressure and temperature are the important variables. It is of enormous
importance in chemistry and in the study of systems where there is a mixture of
two ...

The same term has also been used for the Gibbs' function under analogous
conditions. For example, the difference in standard Gibbs' functions of reactants
and products has often been called the “free energy difference.” Since there is a ...

pressure, and is given as the sum of the Gibbs function for pure water gW(t,p) and
the saline part of the Gibbs function gS(SA ,t,p) so that gSA, t,p ð Þ1⁄4gWt,pð

It can be shown from a combination of the first and second laws of
thermodynamics for a simple compressible system that the Gibbs function of a
system will always decrease or remain the same for a spontaneous process.
Consider the ...

A Course In Thermodynamics
For example, in the case of condensed phases, we shall use the phrase "
standard Gibbs function at 1 atm and 25 °C," and write 298.15 °K). In the case of
gases, we have 9i(P, T) = rf(D + R^ln PIP* where g°(T) = hf(T) - Tsf(T), (e) and
where ...

As shown by the definition, the Gibbs function is a compound property. Like other
thermodynamic properties, the Gibbs function is a function of two independent
properties such as temperature and pressure. For an ideal gas mixture, the Gibbs
