The objective of the paper is to analyze the unsteady free convective flow and mass transfer through a viscous, incompressible, electrically conducting fluid along a porous vertical isothermal non-conducting uniformly moving plate in the presence of exponentially decaying heat generation and transverse magnetic field with variable suction and viscous dissipation. The governing equations of motion, energy and concentration are transformed into ordinary differential equations using similarity parameter method. The ordinary differential equations are then solved numerically using Runge – Kutta method along with shooting technique. Numerical results for velocity, temperature and concentration are obtained for various values of physical parameter and presented graphically. Also the numerical values of skin-friction coefficient, Nusselt number and Sherwood number are obtained for various values of physical parameters discussed and presented through tables.
