What is the Arrhenius Equation Calculator?

The Arrhenius Equation Calculator helps students, chemists, and researchers determine the rate constant of a chemical reaction by using the Arrhenius equation, which relates temperature and activation energy to reaction speed. By entering the pre-exponential factor, activation energy, and temperature, the tool calculates the exponential factor and final rate constant, allowing users to clearly understand how temperature influences reaction rates. This ensures accurate assessment of kinetic behavior and improves understanding of reaction mechanisms.

How to Use:

1. Enter Pre-exponential Factor (A): Input the frequency factor in s⁻¹, which represents molecular collision frequency.
2. Enter Activation Energy (Ea): Input the required energy barrier in kJ/mol.
3. Enter Temperature (T): Input the system temperature in Kelvin.
4. Click “Calculate”: The tool computes the exponent −Ea/RT and the resulting rate constant k.
5. Review Result: The output shows the rate constant, exponent value, converted units, and a comparison table to help interpret the kinetic results.
