An analysis is performed to explore the characteristics of heterogeneous-homogeneous processes for the steady three-dimensional flow of Burgers fluid over a bidirectional stretching surface. In this paper, we utilized the advanced model of a homogeneous-heterogeneous reactions with equal diffusivities for reactant and autocatalysis. Additionally, heat transfer analysis is carried out in the presence of nonlinear thermal radiation and convective boundary conditions. The basic governing non-linear problem is presented and reduced into self-similar form with the aid of suitable similarity approach. The advanced non-linear problem is then tackled analytically by employing the homotpy analysis method (HAM). The effectiveness of relevant physical parameters on temperature and concentration profiles are taken into consideration. It is evident from the graphs that the concentration distribution diminishes by uplifting the homogeneous process parameter while it enhances for strength of Schmidt number. Moreover, it is observed that the surface heat transfer rate enhances for larger values of the Prandtl number.
