โœฆ Synopsis

A single diffusion coefficient, D' applicable to steady-state processes in both equilibrium and non-equilibrium, multicomponent reacting systems is presented. This diffusion coefficient can be used to define the frozen Lewis number in its conventional form. An explicit expression for D' can be obtained in a multicomponent system only in the special case of a single-reaction, multicomponent system with identical binary diffusion coefficients. By analyzing an equilibrium reaction 2ABz z 2AB + Ba (of the type: 2NOa e 2N0 + 02 but with unequal diffusion coefficients) it is shown that D' is insensitive to the thermodynamic state of the system.

Ah&act-While the equilibrium point in an ideal closed reacting system is unique and globally stable, it is shown herein that nonideal systems can have multiple equilibria and that more than one of these can be stable. The simplest kind of nonideality, exemplified by strictly regular solutions, can l
