WEBMay 19, 2018 · Activation energy is the minimum amount of energy required to initiate a reaction. It is the height of the potential energy barrier between the potential energy minima of the reactants and products. Activation energy is denoted by E a and typically has units of kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).
