非电解质溶液二元体系超额热力学函数的测定

Determination of Extra-thermodynamic Function of Nonelectrolyte Soultion Binary System

超额热力学函数的测定，在物理化学的实验教学中，占有相当重要的地位。本文所介绍的内容是利用实验室内的常规仪器，采用化学实验的经典方法，以苯-乙醇混合液为例，测定出超额自由能、超额焓、超额熵等几个超额热力学函数。其方法简便，结果准确，易于实验教学的应用。

it is very important to determine extra-thermodynamic finction in experiment teaching forphysicochemistry. Using general chemical instruments and classical methods, taking miscible liquids ofbeZene-alcohol as an example. extra-free energy, extra-enthalpy and extra-entropy were determined. Themethod was simple and accurate. so it was casily applied in experiment teaching.
