摘要
本文根据粒子间的相互作用力,导出了离解平衡常数的理论公式,并对醋酸在一系列浓度的甲醇水溶液中的离解平衡进行了理论计算.结果表明,本文所求得的 K_a 值要比由 Born 理论和 van derWaals 理论所求得的结果更符合实际.最后对这三个理论进行了简单的分析和讨论.
This article derives a theoretical equation of dissociation equilibrium according to the interaction forces among the particles.The theoretical calculation is made for dissociation equilibri- um of acetic acid in the methanol aqueous solution with a series of con- centrations.The results show practicable values of K_a obtained from the equation in the article in comparison with those from the Born equation and the van der Waals theory.At the end,a brief analysis and account of the three above-mentioned theories are given.
