The primary objective is to enhance understanding of heat transfer rates relevant to applications such as fuel cells, engine cooling systems, pharmaceutical processes, and various engineering industries. In the problem under consideration, the upper plate is squeezing down to the bottom plate, whereas the lower plate exhibits the irreversibly analysis of flow with homogeneous and heterogeneous chemical reactions. When the problem is modeled, the coupled system of partial differential equations is obtained which is transformed into a system of ordinary differential equations by applying the similarity transformation. These resulting equations are solved using the Homotopy Analysis Method (HAM), with appropriate initial conditions and auxiliary parameters to ensure rapid and reliable convergence. The accuracy of the HAM solutions is validated by comparison with results obtained using the numerical solver BVP4c. The study further analyzes effects of the Hall term, entropy generation, variable viscosity, and thermal conductivity on the velocity and temperature distributions in the presence of chemical reactions. https://jcamech.ut.ac.ir/article_102835_e72b4b4022359a96494140476f5b873c.pdf
