The Entropy and Thermodynamic Potentials of Real Gases and Mixtures of Real Gases, and a Mass Action Law for Chemical Reaction Between Real Gases I. General Thermodynamic Relations

Thermodynamic quantities for mixtures of real gases.—Using the two assumptions, that at infinitely low pressures the energies of real gases are additive and the equilibrium pressure is given by the product of the total pressure into the mol fraction, there are deduced general thermodynamic equations for the energy, heat content, entropy, thermodynamic potentials of gas mixtures and the chemical potential of a gas in a mixture in terms of the independent variables $p$ and $T$, and $V$ and $T$.

Mass action law for real gases.—Two forms of the mass action law are deduced depending upon the choice of $p$ and $T$, or $V$ and $T$ as the independent variables.
