**Abstract**

Present study has been carried out to elucidate a laminar free convective flow of an incompressible chemically reactive fluid over an impulsively started vertical plate embedded in a porous medium. The influence of both second order chemical reaction and heat source make the study interesting. The governing coupled partial differential equations are solved by using Crank-Nicolson method. The impacts of pertinent parameters on the velocity, temperature and concentration have been explored through graphs. The results of the present study agree well with the previous solutions. Some important findings are: velocity and concentration profiles decrease with increase in chemical reaction parameter, there is a reduction in temperature with increase in the Prandtl number, temperature improves with higher values of Q. Applications of the present study are shown in material processing systems and chemical industries etc.
