Concept introduction:
The amount of energy required to break a particular bond in one mole of gas molecules is known as bond enthalpy.
Bond enthalpy is directly proportional to the strength of the bond. Higher the bond enthalpy, stronger is the bond.
The breaking of bonds always leads to absorption of energy.
Formation of bonds always leads to release of energy.
The strength of a bond is determined using the values of bond enthalpy.
The process of breaking a bond involves the change of state of the system from higher stability to lower stability, due to which it always requires external energy for its initiation.
The process of formation of a bond involves the change of state of the system from lower stability to higher stability due to which it involves the release of energy.

Consider the reaction 2 S(g) + 3 O2(g) → 2 SO3(g). Using the standard enthalpies of formation listed in Appendix G of your text and the bond energy of 498.4 kJ/mol in molecular oxygen, calculate the average sulfur-oxygen bond energy, in units of kJ/mol, in sulfur trioxide gas. The answer is not 380/381.
Based on the bond energies for the reaction below, what is the enthalpy of the reaction, in kJ? H₂(g) + N₂(g) + 2 C(g) → 2 HCN(g)
Hydrazine, N2H4, burns in oxygen as follows:
N2H4 + O2 → N2 + 2H2O
[The bond energies in kJ/mol are: N-H = 388; N-N 163; N≡N 944; O-H 463; O=O 496]
Draw the chemical structures of the reactants and products and
give the formula to calculate enthalpy change in a reaction, ΔH.
