This equation can be written in dimensionless form as:

, where is the initial concentration ratio, is the dimensionless time, is the mixing time, is the dimensionless concentration, is the Damköhler number (a dimensionless number that is a measure of the reaction time versus mixing time), and is the degree of segregation.

This Demonstration displays the dimensionless concentration versus the dimensionless time for various values of the Damköhler number and the initial concentration ratio. It is straightforward to see that the steady-state dimensionless concentration is independent of the Damköhler number. The Damköhler number has an influence only on how fast this steady-state dimensionless concentration is reached. This steady-state dimensionless concentration is equal to When , there is an analytical expression for the dimensionless concentration, which is given by:

, with .
