Abstract The unsteady radiative flow of chemically reacting fluid over bilaterally stretching surface is under consideration. The surface is convectively heated and influence of thermal and concentration gradients is also taken into account. The resulting nondimensional form of the radiative flow model is obtained after utilizing the feasible set of self-similar variables. Further, model is treated numerically with the help of Runge-Kutta scheme after reduced the model into coupled system of first order initial value problem. Influence of the different flow parameters specially Biot's number, Radiation and chemical reaction parameters are discussed for different values. Also, steady and two dimensional case of the current model is plotted. The graphically comparison between thermal and concentration fields is also provided in the presence and absence of thermal and concentration gradients. Impact of ingrained physical parameters on skin friction coefficient, heat and mass transfer gradients performed numerically. The significant effects of Radiation and chemical reaction parameters on thermal and concentration of the fluid observed. Finally, core findings of the study are mentioned in the last section of the letter.
