In an exothermic chemical reaction, how is energy released?  Usually it is simply expressed as  reactants -> product + energy.  But how is that energy emitted?

I understand the release of electromagnetic energy through photons, but what other vehicles are there?  Do the molecules gain random kinetic energy?  Is it vibrational energy (phonons)?

transfer of kinetic energy is one of the ways, which of course is manifested as heat.  there is also change in mass (by very small amounts)  but to describe this, you need a pretty thorough understanding of quantum physics
