The Gibbs Energy of an Ideal Gas
For an ideal gas of one substance Eq. (4.4-2)
becomes
The molar Gibbs energy, G m , is equal to G/n,
The standard state for the Gibbs energy of an ideal
gas is the same as for the entropy: a fixed pressure
of P ◦ , the standard pressure, defined to be exactly
equal to 1 bar = 100000 Pa. At one time a value
