The unit of activation energy (Ea) is typically expressed in joules (J) or kilojoules per mole (kJ/mol). Activation energy represents the minimum energy required for a chemical reaction to occur by overcoming the energy barrier between the reactants and the transition state. It is a measure of the energy difference between the reactants' energy and the highest energy point along the reaction pathway. |
