Use average bond energies to calculate delta H for the combustion of methane (CH4).


Bond energies are averages, so they are used only to estimate the energy of a reaction. Sample problem #2: Consider the following familiar combustion reaction: CH 4 (g) 2O 2 (g) → CO 2 (g) 2H 2 O (g) (a) Use bond energies to estimate the enthalpy change for the combustion of methane.


Calculations of bond energy? delta H = Energies of bonds broken - Energies of bonds formed.

delta H = 4633 - 5392 = -759 kJ/mol. This is different than the value determined by enthalpy because of the use of average bond energies which are obtained by bonds of gaseous state molecules.


Bond energies of a few calculations are discussed below. C-H bond energy in methane.
