Arrheniusanalyses
Arrhenius analyses refer to methods used in physical chemistry to study the temperature dependence of chemical reaction rates through the Arrhenius equation. They are used to extract kinetic parameters such as activation energy and the pre-exponential factor from measurements of rate constants at different temperatures.
The Arrhenius equation, k = A exp(-Ea/RT), transforms to a linear form: ln k = ln A - Ea/(R
Interpretation: A linear Arrhenius plot supports a single-rate-determining-step mechanism over the tested range. Deviations from linearity
Extensions and alternatives: The modified Arrhenius equation incorporates a temperature-dependent pre-factor, often written k = A T^n
History: Named after Svante Arrhenius, who proposed the exponential dependence of rates on temperature in 1889.
