We say kJ/mol instead of kJ/rxn because. well, just because. I know that doesn’t sound convincing so I found my chemistry book, here’s a quote about it; "It is important to keep in mind that ΔH does not refer to a particular reactant or product. It simply means that the quoted ΔH value refers to all the reacting species in molar quantities."
even for those units on AVT(R). But if FAC is underway, the iron concentration is typically well above that value. Thus, regular iron analyses are critical for establishing and maintaining the correct.

Utility. A-values help predict the conformation of cyclohexane rings. The most stable conformation will be the one which has the substituent or substituents equatorial. When multiple substituents are taken into consideration, the conformation where the substituent with the largest A-value is equatorial is favored.

Chemical Bond Energy Considerations. A chemical bond forms when it is energetically favorable, i.e., when the energy of the bonded atoms is less than the energies of the separated atoms. Some of the types of tabulated data associated with chemical bonds are: Ionization energy: the energy required to remove an electron from a neutral atom. Electron affinity: the energy change when a neutral.
