Taking chemical potential as the main line, this paper mainly introduces the derivation of various types of chemical reaction isotherms both systematically and completely in physical chemistry textbooks. By doing so, it can further consolidate and strengthen the students' understanding and application of the chemical potentials of different kinds of substances. On the other hand, it can also make clear the origin of various types of chemical reaction isotherms rather directly and be helpful to the students for their correct understanding and calculation of standard molar Gibbs free energy change Δ_rG_m^ϴ, standard equilibrium constant K^ϴ (also named thermodynamic equilibrium constant) and reaction quotient Q of various types of chemical reactions. Hence, a rather good teaching effectiveness can be achieved hopefully.
