Energy Diagrams of Reactions | Fiveable To find the activation energy, you should be looking for two numbers: the potential energy of the reactants and the energy of the activated complex (the maximum point). (energy of activation complex) - (PEreactants) (100 kJ) - (40 kJ) = 60 kJ. In other words, it takes 60 kJ of energy to complete the reaction.
Activation Energy - Definition, Formula, Diagram, Examples Activation energy is usually represented by E a and find from the Arrhenius mathematical formula, k = Ae -Ea/RT, where A = constant. It is obvious that the E a in the Arrhenius equation must have the units of energy. Generally, it is measured by the unit like joules per mole (J/mol), kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).
