Bond enthalpies refer to the amount of energy required to break a chemical bond in a molecule or compound. It represents the strength of the bond and is typically expressed in kilojoules per mole.
The average distance between the nuclei of two bonded atoms. Shorter bond lengths are usually associated with stronger bonds.
The same as bond enthalpy, it refers to the amount of energy required to break a chemical bond.
A reaction that absorbs heat from its surroundings, requiring an input of energy. Breaking bonds often involves endothermic processes.
