In general, the relationship between the activity and the mole fraction is examined with time-consuming and elaborate experiments. Gibbs Duhem equation enables the conversion of the activity of one material into that of the other material using integral operation. The time and effort of the experiments could be saved using the equation. In the present report, the procedures for applying the equation are introduced from the fundamental equations to the calculation of the examples.}, pages = {85--89}, title = {11_化学熱力学のすすめ (その 5)}, volume = {56}, year = {2023}, yomi = {ヒグチ, ヨシヒコ} }
