Objectives: To study the unsteady hydro magnetic naturally convicting flow with heat and mass flux in the presence of chemical reaction, fluid past an infinite vertical porous plate with varying temperature and concentration. Statistical Analysis: An analysis is carried out to study the heat transfer in unsteady two dimensional Mass transfer flow of a magneto hydrodynamic over a porous medium. The flow is subjective in the action of uniform transverse magnetic field. With the help of dimensionless variable, the governing flow equation are reduced to a system of nonlinear Partial Differential Equation. This system has been solved analytically using Perturbation Approximation. Findings: The influence of the temperature distribution, concentration distribution, Skin friction coefficient, BrandtNumber, Magnetic Parameter, chemical Reaction Parameter, Gash of number, Modified Gash of Number, Schmidt Number, Heat source Parameter, Radiation Parameter are discussed in Graph. In this paper, suppression of velocity on magnetic Parameter and chemical reaction are discussed. The Gash of Number and Modified Gash of Number increase the velocity, whereas in the literature survey, the analytical or numerical solution obtained by assuming that the temperature at the interface was continuous and well defined. The highlights of the results are helpful to variety the ramped temperature and ramped concentration on the wall of the infinite vertical porous plate. Applications: The combined heat and mass transfer problem along with chemical reaction play a prominent role in chemical and hydrometallurgical industries. It is used by different scientific disciplines for different processes and mechanisms. In many practical situations, mass transfer is accomplished in order to bring chemical reagents together so that a reaction can take place. Thus for example reaction can be used to provide more rapid solution of a gas in to a liquid than physical solution.
