Activation energy of chemical reactions. In this chemical kinetics video lesson, we will describe the concept of activation energy of chemical reactions. We will see how, in the kinetics graph (Energy X reaction path), we can identify the variation in enthalpy and also how to correctly identify the activation energy. It is very important to know how to correctly identify the activation energy of chemical reactions to know which reaction is faster than another. We will also see the difference in activation energy of a direct reaction and the activation energy of the reverse reaction.
