In this new era of fluid field, researchers are interested in hybrid nanofluid because of its thermal properties and potential, which are better than those of nanofluid when it comes to increasing the rate at which heat is transferred. In comparison to the dynamics of chemically reactive Ethylene Glycol - Zinc Oxide (nanofluid) and Ethylene Glycol - Zinc Oxide - Titanium dioxide (hybrid nanofluid) over a moving surface, nothing is known in terms of thermal radiation, entropy formation, viscous dissipation, and the Lorentz force. The thermo-physical characteristics of Ethylene Glycol, Zinc Oxide nanoparticles, and Titanium dioxide nanoparticles are used in this study to derive the governing equations for the transport of both dynamics. Flow-driven equations are transformed into nonlinear ODEs and solved using MATLAB bvp4c solver. It is noticed that, when magnetic field parameter (M) takes input in the range 0 ≤ M ≤ 3, skin friction coefficient decreases at a rate of 0.22052 (in case of hybrid nanofluid) and 0.19203 (in case of nanofluid) per unit value of magnetic field parameter. It is detected that the rise in Brinkmann number causes a rise in entropy generation and Bejan number decreases as Brinkmann number increases. Furthermore, when Eckert number rises, the heat transmission rate decreases. The heat transmission rate drops at a rate of 0.0869 (in case of hybrid Nanofluid) and 0.07429 (in case of nanofluid) when Eckert number (Eck) takes input in the range 0 ≤ Eck ≤ 0.7. The mass transmission rate increases at a rate of 1.013383 (in case of hybrid nanofluid) and 1.013125 (in case of nanofluid) when Schmidt number (Sc) takes input in the range 0 ≤ Sc ≤ 1. A comparison of the current results to previous results indicated a satisfactory agreement under certain conditions. •Irreversibility analysis of hybrid nanofluid flow over a moving plate with chemical reaction and thermal radiation is considered.•Viscous dissipation and Joule heating are also included in the energy equation. Whereas skin friction coefficient decreases as the volume fraction of the nanoparticle increases.•The rise in the value of the chemical reaction parameter correlates to an increase in the mass transfer rate.•An increase in the Brinkmann number results in an increase in entropy generation, but the Bejan number falls as the Brinkmann number rises.
