SUMMARY
The bond energy of O2(g) is 142.0 kJ/mol, which directly relates to calculating the standard enthalpy of formation (deltaH°f) for atomic oxygen (O(g)). To find deltaH°f for O(g), one must halve the bond energy of O2, resulting in a value of 71.0 kJ/mol. This method is based on the principle that breaking the O=O bond produces two O atoms, thus dividing the bond energy by two provides the enthalpy for one O atom.
