### Arrhenius equation

The Arrhenius equation relates the temperature to the rate of a reaction.
|
||||||
|
|
||||||
|
Where:
|
||||||
|
|
||||||
|
- $k$ is the rate constant,
|
||||||
|
- $R$ is the ideal gas constant,
|
||||||
|
- $E_a$ is the activation energy for the reaction,
|
||||||
|
- $A$ is the proportionality/Arrhenius constant for the reaction,
|
||||||
|
- and $e$ is Euler's number
|
||||||
|
|
||||||
|
$$k=Ae^\frac{-E_a}{RT}$$
|
||||||
|
|
||||||
|
Graphing $\ln k$ against $\frac{1}{T}$ forms the linear relation:
|
||||||
|
$$\ln k = \frac{-E_a}{R}\frac{1}{T}+\ln A$$
|
||||||
|
|
||||||
|
where the slope of the graph is $\frac{-E_a}{R}$ and the y-intercept is $\ln A$.
|
||||||
|
|
||||||
|
The number of moles of gas particles that are above the activation energy threshold is expressed in the second term of the equation: $e^\frac{-E_a}{RT}$.
