Values of measured bond energies may vary greatly depending on the molecule studied. Consider the following reactions: N C l 3 ( g ) → N C l 2 ( g ) + C l ( g ) Δ E = 375 k J / m o l O N C l ( g ) → N O ( g ) + C l ( g ) Δ E = 158 k J / m o l Rationalize the difference in the values of ∆ E for these reactions, even though each reaction appears to involve only the breaking of one N—Cl bond. (Hint: Consider the bond order of the NO bond in ONCl and in NO.)
