Abstract: Boundary layer solutions are introduced in order to provide a numerical treatment of nonlinear steady natural convection flow of non-Newtonian micropolar fluid due to an isothermal vertical permeable cone with the impact of homogeneous-heterogeneous reactions. The resulting transformed boundary layer flow equations are solved numerically by the aid of implicit finite difference technique. Additionally, the fluctuations of skin friction, couple stress coefficients and Nusselt number for various interesting sundry parameters are depicted graphically and discussed. From the obtained results, the coefficient of couple stress increases for larger values of surface temperature exponent n whereas reverse trend is clarified through vortex viscosity parameter K. Once again, it is found from current contribution that concentration of the micropolar fluid is decreases function by increasing the strength of homogeneous and heterogeneous reactions. The code of numerical technique is validated by comparing our data with previous published contributions and a good agreement is given.
