平衡常数作为开放化学体系的解

Equilibrium Constant as Solution to the Open Chemical Systems

B. Zilbergleyt

摘要:

根据当代观点,平衡常数只与具有一个化学反应的孤立系的真正热力学平衡有关。本文提出了一个新的公式,可以将孤立态和开放态的平衡常数与化学体系组成联系起来。扩展了化学平衡离散热力学的对数逻辑图,该公式将孤立平衡时的系统种群映射为p,T=const时的任何开放平衡时的种群,使用平衡常数作为度量。真实的化学系统包括多个子系统;给定资源是有限的,对这些表达式的集合的联合求解,每个表达式与特定的子系统相关,给出每个子系统的平衡组成。这一结果意味着在开放体系热力学中的一个根本性突破,并为实际化学对象的分析带来了以前未知的机会。

英文摘要:

According to contemporary views, equilibrium constant is relevant only to true thermodynamic equilibria in isolated systems with one chemical reaction. The paper presents a novel formula that ties-up equilibrium constant and chemical system composition at any state, isolated or open as well. Extending the logarithmic logistic map of the Discrete Thermodynamics of Chemical Equilibria, this formula maps the system population at isolated equilibrium into the population at any open equilibrium at p,T=const, using equilibrium constant as a measure. Real chemical systems comprise multiple subsystems; given the resources are limited, joint solution to the set of such expressions, each relevant to a specific subsystem, gives equilibrium composition for each of them. This result means a fundamental break through in the open systems thermodynamics and leads to formerly unknown opportunities in the analysis of real chemical objects.
