## Arrhenius Equation

The following formula is used to calculate the rate constant of a reaction using the Arrhenius euqation.

K = A * e^(-Ea/ R * T)

- Where K is the rate constant (sec^-1)
- A is the frequency factor (sec^-1)
- Ea is the activation energy (kj mol^-1)
- T is the temperature (K)
- R is the gas constant ( 8.314*10^-3 kj mol^-1 K^-1)

## Arrhenius Equation Definition
