*4.3. Concentration of Homogeneous-Heterogeneous Chemical Reactions*

Looking at the non-dimensional Equation (28), the suitable values of *Re*, *Sc* and *k*<sup>4</sup> are the basic quantities for generating a cubic autocatalysis chemical reaction. The concentration of chemical reaction *ϕ*(*ζ*) is low with the Reynolds number *Re* as shown in Figure 20. Figure 21 shows that for the homogeneous chemical reaction parameter *k*4, the concentration of chemical reaction is decreased. From Equation (28), it is witnessed that the homogeneous chemical reaction parameter *k*<sup>4</sup> is a part of performance with the multiple solutions. Enhancement in *k*<sup>4</sup> makes dominant the concentration. In Figure 22, the stretching parameter *k*<sup>6</sup> upgrades concentration of chemical reaction with low level by performing active role in the rotating motion. The stretching parameter *k*<sup>6</sup> makes compact the homogeneous reaction and hence the concentration profile *ϕ*(*ζ*). Figure 23 stands for the outcomes of Schmidt number *Sc* and concentration *ϕ*(*ζ*). Momentum diffusivity to mass diffusivity is known as Schmidt number. The parameter *Sc* causes to make low the homogeneous chemical reaction.
