Abstract:

For a reaction occurring between volatile solutes in a solution system, the calculation of the Gibbs function is fundamentally different from that of other reaction systems. This paper discusses the calculation of the Gibbs function and suggests that the significant difference in the calculation should be indicated in physical chemistry textbooks to avoid possible errors in teaching and application.

Key words: Standard molar Gibbs function of chemical reaction, Solution system, Volatile solute, Calculation
