WebApr 11, 2024 · Well, the activation energy is the extra energy given to get useful work done. In chemistry, we call it the minimum amount of energy (or threshold energy) needed to activate or energize molecules or atoms to undergo a chemical reaction or transformation. The activation energy units are LCal/mo, KJ/mol, and J/mol. Concept of Activation Energy WebJan 1, 2015 · Since the electron belongs to the orbitals of many other atoms, and not only one or two (as in the case of the H-H covalent bond), it holds all these six carbon atoms in place, and thereby acts as a bond between the six carbon atoms, which in turn brings stability to the system and lowers its potential energy.
