When do I use k = A·e^(−Ea/RT) in Chemical Kinetics, and what does it mean?

Arrhenius equation linking rate constant to temperature.

k = A·e^(−Ea/RT) — Arrhenius equation linking rate constant to temperature. Use it when: Ea is the activation energy. Always check the condition holds before plugging in numbers.

Key point

k = A·e^(−Ea/RT)
