Arrhenius equation

[ar′rā·nē·əs i′kwā·zhən]
(physical chemistry)
The relationship that the specific reaction rate constant k equals the frequency factor constant s times exp (-Δ Hact/ RT), where Δ Hactis the heat of activation, R the gas constant, and T the absolute temperature.

Relaxation times for PPy and its composites, determined with respect to Arrhenius' law decreased linearly with increasing temperature.
The reaction rate constant increases exponentially with elevation of temperature following Arrhenius' law. If the relative humidity affects the water content of the collection medium, the diffusion coefficient in the liquid phase and the reaction rate constant may be changed.
The temperature dependency of the relaxation time is usually analyzed using Arrhenius' law:
The constitutive equation and its temperature dependency are represented by the Carreau model and Arrhenius' law.
