The Temperature Dependence of the Gibbs
Energy Change
The temperature derivative of the Gibbs energy is
given by Eq. (4.2-20):
However, we cannot use this equation to calculate a
value of ∆G for a temperature change because the
value of the entropy can always have an arbitrary
constant added to it without any physical effect. We
can write an analogous equation for the temperature
dependence of ∆G for an isothermal process:
