Question
What is bond enthalpy? Bond enthalpies of polyatomic molecules are average values, whereas those of diatomic molecules can be accurately determined. Why?
Step 1
Bond enthalpy, also known as bond energy, is the measure of bond strength in a chemical bond. It is defined as the amount of energy required to break one mole of the bond in the gaseous state. It is usually expressed in units of kilojoules per mole (kJ/mol). Show more…

What is bond energy? How can you use average bond energies to calculate enthalpies of reaction?
Explain why the bond enthalpy of a molecule is usually defined in terms of a gas-phase reaction. Why are bond-breaking processes always endothermic and bond-forming processes always exothermic?
