The bond enthalpy in no is 632 kj/mol and that of each no bond in no2 is 469 kj/mol. explain the difference in bond enthalpies between the two molecules. 1. the bond type does not explain the difference. 2. no has a singl

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. 

The correct answer is b
