Values of measured bond energies may vary greatly depending on the molecule studied.

Chapter 9, Problem 99CP
Textbook Problem

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.)
