6.4.1: Eyring equation - Chemistry LibreTexts
2023年2月13日 · 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 …
The Eyring Equation G RT h k T k B / rxn = e−Δ ‡ S R H RT h k T k B / / rxn = eΔ ‡ e−Δ ‡ ΔG‡ = ΔH‡ –TΔS‡, so Eyring equation. Relates rate constant to T in a physical way. ΔH‡: Enthalpy required to reach transition state (like E a) ΔS‡: Entropy lost/gained getting to transition state
Eyring equation - chemeurope.com
The Eyring equation also known as Eyring-Polanyi equation in chemical kinetics relates the reaction rate to temperature. It was developed almost simultaneously in 1935 by Henry Eyring, M.G. Evans and Michael Polanyi.
To obtain a mathematical expression for the kinetic isotope effect we can use either the Arrhenius equation or the Eyring equation from transition state theory. Using the Arrhenius equation, the rates for the two isotopomers are kH = AH exp[ EA(H)/kBT] kD = AD exp[ EA(D)/kBT]

Equation \(\ref{Eyring}\) is known as the Eyring Equation and was developed by Henry Eyring in 1935, is based on transition state theory and is used to describe the relationship between reaction rate and temperature.
∆G‡ is, of course, calculated directly from k and the Eyring equation. That is to say that one can readily translate between the two ways of describing the rate of a reaction: ∆G‡ or k. we obtain a strictly linear realtionship which can be plotted. The Eyring equation as normally written.
Eyring equation - Oxford Reference
5 天之前 · The Eyring equation is named after Henry Eyring, who derived it and applied it widely in the theory of chemical reactions and transport processes. κ = K (kT / h)exp (–Δ G ‡ / kT) An equation used extensively to describe chemical reactions.
