极性气体分子缔合平衡常数、缔合焓和缔合熵方程的研究

DEVELOPMENT OF EQUATIONS FOR CALCULATING THE EQUILIBRIUM CONSTANT, ENTHALPIES AND ENTROPIES OF ASSOCIATION FOR POLAR GASES

一、前言 根据我们提出的分子聚集理论,认为分子聚集现象是流体的一种普遍现象,这种分子聚集行为的存在,对物质的物理化学性质有很大影响。本文首先是对流体单体分子形成聚集体分子的机制进行分析研究,然后应用分子聚集理论推导出极性气体的缔合平衡常数、缔合焓和缔合熵方程。显然,这一研究成果不仅在物理化学。

Based on the analysis of the molecular association phenomenon of some polar gases, equations for calculating equilibrium constant, enthalpies and entropies of association for gases are developed. In addition, the simple truncated virial equation of state, describing PVT behavior of gases at low pressure is improved. These equations have been tested, giving satisfactory results.
