Partial Molar Quantities of a One-Component Ideal
Gas
As with any pure substance the partial molar volume
of a one-component ideal gas is equal to the molar
volume:
The chemical potential of a one-component ideal gas
is equal to the molar Gibbs energy. From Eq. (4.4-5),
Where G ◦ m is the molar Gibbs energy in the standard
state. It is equal to µ ◦ , the chemical potential in the
standard state. The standard state for the Gibbs
energy of an ideal gas is the ideal gas at pressure P ◦
(exactly 1 bar).
