Application of tracer information to reactors

In contrast to this, when a solution of a substance is diluted, the molecules of the solute mix on a molecular scale with fresh solvent and essentially lose their identity in the process. This is called micromixing. In the same way solutions of two different solutes can undergo micromixing. 

Reaction order 1, reaction rate is greatest with complete segregation. 

The significance of early or late mixing may be seen from the example given by
