Description

the code does not now include energy exchange due to chemical reactions. All chemical processes will be either endothermic or exothermic and heating/cooling terms need to be added to account for the thermal effects of the chemistry.

Chemical heating/cooling is not part of the standard PDR literature (all other codes similarly neglect it) but it could be important. This was not done in the original coding of the chemistry because energy differences would need to be introduced for each of the thousands of reactions that occur.

this should be straightforward with newmole. We could store an energy (relative to some definition of zero energy) for every species. Then the energy exchange would be the sum over rates, populations, and the energy differences between all the species in a reaction.

could this problem be part of the energy problems we have for some sims?
