I said:

I am neglecting the energy associated with the chemical bonding, but oftentimes even the bonding energy will later be liberated and dissipate as heat.

And you said:

You know, you might want to consider which vibrational-rotational states the reactants and products in the reaction are in as well ;-)

Yes, and I could solve Schrodinger's equation to figure this out, if the boundary conditions are provided, to show off my knowledge -- but this is excessive.

My point is related to thermodynamics concerning the direction of processes. The natural tendency is to increase the entropy and local decreases of entropy (moving away from equilibrium) only occur when the boundary conditions are controlled in some fashion. Typically complex boundary conditions require intelligence to setup.

Sorry 'bout that, nas...

My concern was with the word "later"--depending on the quantum state your products are in at the time they are produced, you might get your heat back "immediately".

Cheers!
