Arrhenius Number

Arrhenius number ( \(Ar\) ) (dimensionless number) is used in mass transfer in general, and reaction rate calculations in particular.

Arrhenius Number FORMULA

\(\large{ Ar = \frac {E_a}  {RT} }\)         

Where:

\(\large{ Ar }\) = Arrhenius number

\(\large{ E_a }\) = activation energy

\(\large{ R }\) = universal gas constant

\(\large{ T }\) = temperature
