Abstract This study investigates electro‐osmosis in an Oldroyd‐B fluid with a nonlinear Arrhenius reaction to model temperature‐dependent chemical kinetics, enhancing concentration predictions. Similarity transformations reduce the governing equations to ODEs, solved via a MATLAB‐based shooting technique and RungeKutta method. The analysis highlights the combined effects of electro‐osmosis, MHD flow, radiation, melting, and nonlinear reactions. Results reveal the interplay of these mechanisms, offering insights into thermal transport and microfluidic applications, with implications for engineering and industrial processes involving complex fluids.
