Activation energy.


Activation energy can be defined as the magnitude of the potential barrier (sometimes referred to as the energy barrier) that separates minima from the potential energy surface of the initial and final thermodynamic state. In order to proceed at a reasonable rate for a chemical reaction or division, the system temperature should be sufficiently high so that there is a significant number of molecules with translational energy equal to or greater than the activation energy. In joules per mole (J / mol), kilojoules per mole (kJ / mol), or kilocalories per mole (kcal / mol), the activation energy ( Ea) of a reaction is calculated.
