Activation Energy Calculator









Formula

To calculate the Activation Energy (E):

\[ E = -R \times T \times \ln\left(\frac{k}{A}\right) \]

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.

Example Calculation

Let's assume the following values:

Step 1: Use the activation energy calculation formula:

\[ E = -8.314 \times 298 \times \ln\left(\frac{0.001}{0.01}\right) \approx 5704.56 \text{ J/mol} \]

The Activation Energy is approximately 5704.56 J/mol.
