# Arrhenius Equation

Written by Jerry Ratzlaff. Posted in Thermodynamics

Arrhenius Equation is the temperature dependance of the reaction rate constant.

## FORMULA

$$k = Ae \frac {-Ea}{RT_a}$$

Where:

$$k$$ = rate constant

$$A$$ = frequency factor (different for every reaction)

$$e$$ = natural log base

$$E_a$$ = activation energy

$$R$$ = universal gas constant

$$T_a$$ = absolute temperature
