Activation Energy Calculator

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?
