| Abstract
| - We consider the transport of multiple reacting species under the continuum assumption in situations such asthose that frequently arise in electroanalytical chemistry. Under certain limitations, it has been shown that thetotal species concentration (as defined by Oldham and Feldberg) of such a system is uniform and constant.In this work, we extend the limits of the previous analysis to enable greater applicability. This is accomplishedby using either of two new dependent variables, which are generalizations of the concept of total concentration.Then, conditions are determined under which the dependent variable will be uniform and constant in time.From a practical viewpoint, the described formalism allows one to simplify the multispecies transport problemformulation by eliminating one equation from the system of governing equations.
