Activation energy must be considered when analyzing both endergonic and exergonic reactions. Exergonic reactions have a net release of energy, but they still require a small amount of energy input before they can proceed with their energy-releasing steps.

The recently introduced activation strain model (ASM) of reactivity has allowed us to gain more insight into the intimacies of different fundamental processes in chemistry.[1] In combination with the energy decomposition analysis (EDA) method,[2] The activation energy of a chemical reaction is the minimum energy that is needed to make the reaction happen. It usually has the symbol Ea and it is measured in kilojoule per mole. It can be thought of as a barrier between the reagents and the products of a reaction.

Activation energy: Activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In chemistry, activation energy is the energy which must be available to a chemical system with potential reactants to result in a chemical reaction. Activation energy may also be defined as the minimum energy required to start a chemical reaction. La b.
