## Arrhenius equation

https://doi.org/10.1351/goldbook.A00446
An equation that represents the dependence of the @R05138@ $$k$$ of a reaction on the absolute temperature $$T$$: $k = A\ \text{e}^{\frac{-E_{\text{a}}}{R\ T}}$ In its original form the @P04811@ $$A$$ and the @A00102@ $$E_{\text{a}}$$ are considered to be temperature-independent.
