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) = ΔEa/RT2 where Ea is the activation energy and R is the universal gas constant.

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.

In this study, it was assumed that hydrolysis was the primary mechanism of degradation for the samples and that the temperature dependence of the rate followed Arrhenius' law as [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] where k = rate constant; A = constant; [E.
The reaction rate constant increases exponentially with elevation of temperature following Arrhenius' law.
However, Ni with higher activation energy is very temperature-sensitive, according to Arrhenius' law.
