Definition
Bond energies represent the amount of energy required to break a specific type of chemical bond, or the energy released when that bond is formed. They are typically reported in kilojoules per mole (kJ/mol).
A chemical bond is an attractive force that holds atoms together in molecules or ions.
Energy Release: Energy release refers to the liberation of energy during a chemical reaction or physical process.
Kilojoules per Mole (kJ/mol): This unit quantifies the amount of energy required or released on a per-mole basis, allowing for easier comparison between different substances and reactions.
