The idea of this work is to explore the impact of endothermic and exothermic chemical reactions on time-dependent magnetohydrodynamic nanomaterial flow, heat and mass transfer characteristics induced by a rotating sphere. Implementing combined influence of chemical reaction and activation energy is vital for improving the efficiency of thermal transmission processes in different industrial applications including energy production, pollutant control system, material processing, etc. Owing to its usage, this investigation aims to examine the influence of endothermic, exothermic reactions and activation energy on the flow of Magnetohydrodynamic over a rotating sphere with the nanoparticles that contains a mixture of water and titanium oxide. Furthermore, this investigation studies the influence of activation energy on both heat and mass transfer in fluid systems. The objective is to boost our insight into difficult problems, which could have real-world usages in areas including combustion engines. The PDEs were transformed into ODE via applying similarity variables and then solved using the BVP4c technique. This study shows that the fluid temperature reduces the reaction rate and improves the activation energy for an exothermic reaction. Also, in the case of an endothermic reaction, the fluid temperature increases the reaction rate and reduces the activation energy. Further, in exothermic reactions, the heat distribution rate is higher than endothermic reactions, considering activation energy and solid volume fraction while the mass transfer rate declines for improved values of these two factors.
