Birk-Perone reaction

E.3.9 A Nonlinear System Programs for the Birk/Perone Reaction... 

The Birk-Perone system, a flash photolysis experiment with subsequent second-order decay, is a little more interesting because it can, with an unsuitable simulation method, lead to negative concentration values. The simultaneous reactions are... 

One of the problems mentioned in Chap. 8 is that of second-order homogeneous chemical reactions, which give rise to nonlinear terms in the transport equations. One such system is the Birk and Perone reaction [10, 11], in which a light flash produces an electroactive substance in solution, which decays with a second-order reaction while it is electrolysed. If CN is used to simulate this, the term in Cj can be linearised to a good, second-order approximation. If one does not choose or is prevented from linearisation, a Newton approach, as described in that chapter, must...
