How it works
Fill in the 3 fields above and Arrhenius Equation Calculator calculates the result instantly, recalculating as you change any value. It applies the formula k = A·e^(−Ea/RT). The math runs locally in your browser — nothing is sent to a server.
Formula
k = A·e^(−Ea/RT)Examples
- Pre-exponential factor (A) 10000000000000, Activation energy 75000 J/mol, Temperature 298 K → Rate constant k: 0.7132 s⁻¹
