The Eyring-Polanyi equation offers significant advantages over the Arrhenius equation due to its derivation from the microscopic mechanism of chemical reactions, incorporating more parameters such as entropy and enthalpy. In contrast, the Arrhenius equation is purely empirical and relies solely on activation energy. The logarithmic transformation of both equations reveals a linear relationship for the Arrhenius plot, while the Eyring-Polanyi equation exhibits a slightly nonlinear relationship. Researchers can derive an Arrhenius-like approximation to the Eyring-Polanyi equation by analyzing the slope and offset of the tangent line at a specific point on the logarithmized curve.
