This study analyses Laplace transforms method on a system of partially coupled differential equations for non-isothermal chemically reactive flow through a cylindrical channel. The dimensionless governing equation for velocity, temperature and concentration was solved using Laplace Transform. Various parameters such as Temperature boundary parameter, Concentration boundary parameter, Cooling Parameter, Grashof number, pressure gradient and Magnetic field, as well as perturbation parameter had an effect on the velocity profile as well as temperature and concentration profile. The graphs were obtained with the results showing that an increase in the temperature boundary parameter resulted to an increase in the temperature of flow, an increase in perturbation parameter resulted to an increase in temperature profile of a body and an increase in Grashof temperature number results to an increase in the velocity of the body.
