Arrhenius equation

Temperature dependence of reaction rates:

$$k=A{e}^{-E_a/RT}$$

where:

• $k$: rate constant (frequency of collisions resulting in a reaction),
• $A$: pre-exponential factor/Arrhenius factor/frequency factor,
• $E_a$: molar activation energy for the reaction,
• $R$: universal gas constant,
• $T$: absolute temperature.

$$\to \ln k=\ln A-\frac{E_a}{R}\cdot \frac{1}{T}$$
