Stability A Unifying Concept

When this condition is fulfilled, the system is thermodynamically inert, i.e., the reaction under consideration is impossible.  

For defining an intrinsic stability of a chemical species we start from the common assumption (Cox and Pilcher, 1970) that the heat of atomiza- 

Now we assume that the heat of atomization of some species, which we will refer to as reference compounds, is simply a sum of chemical bond energies or bond energy terms supposed to be constant and transferable from one species to another. Thus, for these reference compounds, Eq. (77) becomes  

It allows us to determine a wide variety of bond energy terms from the experimental heats of atomization of reference compounds. 

Before we analyze the results obtained for a large variety of compounds, we recall the main formulas we have previously deduced for calculating the stabilization energy of neutral species, molecules and free radicals, and of ionic species, carbocations and carbanions. Furthermore,
