Bond enthalpy or bond energy is the amount of energy that is needed in order to break or take out one mole of the substance. The bond energy is varied between the compounds NO and NO₂ because of the different configuration of the atoms in order to form the compound.

That being said, it is also noted that the bonds will have different lengths and the molecules will have different shape and are also composed of different numbers of atoms.
