What is the Arrhenius Equation?
The Arrhenius equation is written as follows:
k = Ae-Ea / RT
In the above equation,
k is rate constant
A is the pre-exponential factor
Ea is the activation energy for the reaction per mole of the reactants
R is the universal gas constant
T denotes the absolute temperature of the reaction in Kelvin (K)
The above equation may also be written as follows when the energy is taken as energy per molecule of the reactants.
k = Ae-Ea / kbT
where
kb represents the Boltzmann constant.
Arrhenius Equation
The Arrhenius equation establishes a link between a chemical reaction’s rate constant and absolute temperature, incorporating the A factor, or pre-exponential factor. This factor represents the frequency of reactant particles colliding in the correct orientation. The equation highlights how reaction rates are influenced by changes in temperature, illustrating the temperature dependency of chemical processes. Let us look at the Arrhenius equation in detail in this article.
