The present study explores the influences of chemical reaction and viscous dissipation on the hydromagnetic squeeze flow of Jeffrey fluid in channel over porous medium by slip boundary. The nonlinear partial differential equations are converted to the nonlinear ordinary differential equations using dimensionless variables and solved through numerical approach of Keller-box. The results of skin friction coefficient, Nusselt and Sherwood numbers are compared with existing results in the journal for validation of the present results. Comparison shows that the numerical outputs are in excellent agreement. Findings indicate that wall shear stress and fluid velocity increase as the plates approaching each other. Also, increment of Hartmann number (from 0.5 to 6.5) and ratio of relaxation and retardation times decrease the velocity, temperature and concentration profile. The effect of viscous dissipation elevates the heat transfer rate and temperature profile. Besides, mass transfer rate drops in convective chemical reaction and opposite impact is noticed in destructive chemical reaction.
