非平衡化学依赖性的平衡关系
Equilibrium relationships for non-equilibrium chemical dependencies
摘要:
与一般观点相反,它表明,平衡常数确定的特定比例的浓度的可逆一级反应的任何系统的时间依赖性行为。事实上,某些特殊的比率实际上在任何时刻都与平衡常数相一致。这是建立间歇式反应器,类似的关系保持稳态活塞流反应器,停留时间取代天文时间。这种关系可以称为化学动力学的时间不变量。
英文摘要:
In contrast to common opinion, it is shown that equilibrium constants determine the time-dependent behavior of particular ratios of concentrations for any system of reversible first-order reactions. Indeed, some special ratios actually coincide with the equilibrium constant at any moment in time. This is established for batch reactors, and similar relations hold for steady-state plug-flow reactors, replacing astronomic time by residence time. Such relationships can be termed time invariants of chemical kinetics.
