Bond energies can be used to estimate the enthalpy change of a reaction. The equation for the combustion of methane \(\ce{CH4}\) is shown below:
\(\ce{CH4(g) + 2O2(g) -> CO2(g) + 2H2O(l)}\)
Given the following bond energies:
- \(\ce{C-H}\) bond: 412 kJ mol\(^{-1}\)
- \(\ce{O=O}\) bond: 498 kJ mol\(^{-1}\)
- \(\ce{C=O}\) bond: 805 kJ mol\(^{-1}\)
- \(\ce{O-H}\) bond: 463 kJ mol\(^{-1}\)
Calculate the total bond energy of the products. (2 marks)
