But, before the reactants can be converted into products, the free energy of the system must overcome the activation energy for the reaction, as shown in the figure below. The vertical axis in this diagram represents the free energy of a pair of molecules as a chlorine atom is transferred from one to the other.

Notes on Kinetics Activation Energy What is Activation Energy? Every reaction requires a certain minimum energy for the reaction to occur--it is called activation energy, Ea, and is expressed in kJ.

These two reactions can be discussed in terms of the activation energy and its effect on the rate of a chemical reaction. This concept can be related to many practical observations such as catalytic converters in automobiles exhaust systems and the fact that most things around us ate unstable with respect to combustion.
