The Eyring equation (occasionally also known as Eyring–Polanyi equation) is an equation used in chemical kinetics to describe the variance of the rate of a chemical reaction with temperature. It was developed almost simultaneously in 1935 by Henry Eyring, Meredith Gwynne Evans and Michael Polanyi.


The Eyring Equation, also called the Eyring-Polanyi Equation, is used to calculate the rate of a chemical reaction at different temperatures in the field of chemical kinetics. It is written as k = (k_b[t])/h) * e^(-delta.G/Rt). The Eyring Equation was developed in 1935 by theoretical chemist Henry Eyring.


The Eyring Equation, developed by Henry Eyring in 1935, is based on transition state theory and is used to describe the relationship between reaction rate and temperature. It is similar to the Arrhenius Equation, which also describes the temperature dependence of reaction rates. However, whereas Arrhenius Equation can be applied only to gas ...

The Eyring equation is also used in the study of solution reactions and mixed phase reactions - all places where the simple collision model is not very helpful. The Arrhenius equation is founded on the empirical observation that rates of reactions increase with temperature. The Eyring equation is a theoretical construct, based on transition ...


This makes me think that the Eyring equation is simply using the unitless values of these variables. This still leads to some ambiguity about which value of the rate constant to use. Take for instance a second-order reaction in which the rate constant is in units of $\mathrm{M^{-1}\ s^{-1}}$.


The third part of equation (2) contains the activation free enthalpy dG** of the reaction which, according to equ. (3) is directly related to the activation enthalpies and activation entropies: dG** = dH** - TdS** (3) The activation parameters of the Arrhenius and Eyring equations of a first order reaction are related as follows:


used reverberation time equation is the Sabine equation (Sabine 1992). In the following years several revised equations were proposed like the Eyring or the Millington equations (Eyring 1930; Millington 1932). The purpose of this study was to test the use of the Sabine and Eyring equations in churches

Arrhenius equation gives the dependence of the rate constant of a chemical reaction on the absolute temperature, a pre-exponential factor and other constants of the reaction. = −, where k is the rate constant, T is the absolute temperature (in Kelvin), A is the pre-exponential factor, a constant for each chemical reaction.According to collision theory, A is the frequency of collisions in the ...
