- The Arrhenius equation allows us to calculate activation energies if the rate constant is known, or vice versa. As well, it mathematically expresses the relationships we established earlier: as activation energy term Ea increases, the rate constant k decreases and therefore the rate of reaction decreases.
How to Find Activation Energy: Instructions & 6 Examples
- https://www.wikihow.com/Find-Activation-Energy
- In the Arrhenius equation [k = Ae^ (-E_a/RT)], E_a represents the activation energy, k is the rate constant, A is the pre-exponential factor, R is the ideal gas constant (8.3145), T is the temperature (in Kelvins), and e is the exponential constant (2.718). You can rearrange the equation to solve for the activation energy as follows: [3]
