Photosensitive BZ and CDIMA Reactions

As discussed in Sect. 1.4.8, the BZ reaction is well described by the two-variable Oregonator model (1.131). The BZ reaction is photosensitive if Ru(bpy)3 is used as the catalyst. The effect of illumination can be modeled by a modification of (1.131) [237]  

The steady states of an isolated reactor are given by Py = p., where p is a root of the cubic equation  

Equation (13.162) has unique, physically acceptable solution if the stoichiometric parameter h is large enough. 

The effect of illumination on the CDIMA reaction can be taken into account by a modified two-variable Lengyel-Epstein model [98]  

The kinetic equations preserve positivity, see (1.2), if the light intensity satisfies
