relationship between the two models. Nevertheless, the functional forms of the Arrhenius and Eyring equations are similar, and for a one-step process, simple and chemically meaningful correspondences can be drawn between Arrhenius and Eyring parameters.

Instead of also using E_a, the Eyring equation uses the concept of Gibbs energy and the symbol ?G^? to denote the Gibbs energy of activation to achieve the transition state. In the equation,
