Arrhenius equation

Ar·rhe·ni·us e·qua·tion

(ă-rē'nē-ŭs), an equation relating chemical reaction rate (k) to the absolute temperature (T) by the equation: d(ln k)/dT) = ΔE_a/RT² where E_a is the activation energy and R is the universal gas constant. [Svante Arrhenius]

Arrhenius equation

(ă-rā′nē-us) [Svante Arrhenius, Swedish chemist and Nobel laureate, 1859–1927] A mathematical formula that specifies the influence of temperature on the rate of a chemical reaction. In general, a higher temperature produces a faster reaction. The equation is used in industry and pharmacy to predict shelf life of reagents and pharmaceuticals.
