Arrhenius Equation

Temperature dependence of the reaction rate constant.

Formula

k=Ae−Ea/RTk = A e^{-E_a/RT}

Variables

APre-exponential factor
E_aActivation energy
RGas constant
TTemperature

Example

Reaction rates roughly double for every 10 °C rise — the Arrhenius temperature effect.

Did You Know?

The Arrhenius equation explains why food spoils faster in warmth — reactions speed up sharply with temperature.
