To calculate the bond energy for diatomic oxygen (O2), we will make use of the equation:
Bond Energy = ΔH / Number of moles of bonds broken
In the case of diatomic oxygen (O2), we have one mole of O2 containing one bond, so the number of moles of bonds broken is also equal to 1.
Given that the standard enthalpy of atomization of oxygen (ΔH) is 249.17 KJ, we can substitute these values into the equation:
Bond Energy = ΔH / Number of moles of bonds broken
= 249.17 KJ / 1
= 249.17 KJ
Thus, the bond energy for diatomic oxygen (O2) is 249.17 KJ.
