基于化学平衡的热力学要求、麦克斯韦关系和吸附相的熵，提出了估计吸附质（蒸气）和吸附剂（固体）之间的等量吸附热的理论框架。导出的等量吸附热方程根据文献中发现的三组明智选择的吸附剂+吸附物数据进行验证，并且发现预测与报告数据的实验不确定性一致。 (c) 2006 年美国物理研究所。
A theoretical framework for the estimation of the isosteric heat of adsorption between an adsorbate (vapor) and an adsorbent (solid) is proposed based on the thermodynamic requirements of chemical equilibrium, Maxwell relations, and the entropy of the adsorbed phase. The derived equation for the isosteric heat of adsorption is verified against three sets of judiciously selected adsorbent+adsorbate data that are found in the literature and the predictions are found to agree within the experimental uncertainties of the reported data.
