This paper examines the chemical reaction sparked by activation energy across a porous regime together with an unstable, three-dimensional rotating flow of non-Newtonian nanofluid. It is intended for the medium filled with a rigid Casson Williamson nanofluid. The Navier-Stokes partial differential equations undergo a similarity transformation to become ordinary differential equations, which are then numerically evaluated for the momentum, energy, and moisture distributions using the fourth-order Runge-Kutta-Fehlberg scheme via shooting approach. Good accuracy for the current results was achieved by comparing them with the prior works. In addition, the drag forces, heat, and mass transmission rates are computed numerically and tabulated near the surface. Analysis shows that an increase in the local Nusselt number indicates a higher energy transmission pace, which is correlated with a rising Prandtl number, stretching ratio parameter, and porous medium parameter. Meanwhile, rising values of the rotation parameter enhance mass transmission by 60.54, while climbing values of the stretching ratio parameter promote heat transmission by 37.87. Three-dimensional surface plots are utilized to illustrate the impact of the Sherwood number due to changes in the Lewis number and activation energy parameter. Furthermore, Casson Williamson nanofluid is more viscous than other fluids, so it tends to slow down the flow rate. A molding of polymer sheets, emulsion-coated layers, fiber glass manufacture, plastic film painting, and other processes can all benefit from these discoveries in terms of chilling the sheet more quickly.
