This paper scrutinized the impact of isothermal quartic autocatalytic form of chemical reaction have on a ternary hybrid nanofluid. In view of the nature of chemical reaction that is to take place in the system, a sizeable amount of heat is to be generated into the system, which will have an influence on some of the fluid properties. As such, fluid viscosity and thermal conductivity were considered to be temperature dependent. The ternary hybrid nanofluid was prepared by injecting ternary nanoparticles (Al2O3, SiO2 and Ag) into a non-Newtonian base fluid. The third-grade fluid model was employed to model the non-Newtonian base fluid. The governing equations formed a system of coupled differential equations. Numerical solutions were obtained using shooting approach executed in Matlab. The results obtained showed the effect of major parameters on the fluid flow, heat transfer and diffusion rate.
