Enter the temperature, rate coefficient, and constant. The activation energy calculator will evaluate and display the total activation energy.

## Activation Energy Formula

The following equation can be used to calculate the activation energy of a reaction.

E = -R * T * ln(k/A)

- Where E is the activation energy
- R is the gas constant
- T is the temperature
- k is the rate coefficient
- A is the constant

## What is Activation Energy?

Activation Energy is the total energy needed for a chemical reaction to occur. It’s most often used in chemistry and thermodynamics. These reactions can include things like combustion.
