exothermic reaction
Let an agent explain exothermic reactions and their thermodynamics, describe examples and applications, explain thermal runaway and its prevention in batteries and processes at a general level, and support learning in chemistry.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain exothermic reactions and their thermodynamics, describe examples and applications, explain thermal runaway and its prevention in batteries and processes at a general level, and support learning in chemistry.
A chemical reaction that releases energy, usually as heat, to its surroundings, such as combustion, neutralisation, many oxidation reactions and setting of cement, with a negative enthalpy change, in contrast to endothermic reactions that absorb heat; exothermic reactions power engines and heating, are used in hand warmers and self-heating products, and can lead to thermal runaway in batteries and reactors when heat accelerates the reaction faster than it can be removed.
What it is for: Reactions releasing heat.
It can be explain thermodynamics; describe examples and applications; explain thermal runaway generally; support learning.
Distinguishing features
Heat release
Negative enthalpy
Common in combustion
Runaway risk
What it looks like
Not physical as a concept; seen as heat, flame or warming.
How it is recognised
Releases heat to surroundings
Negative enthalpy change
Endothermic reactions absorb heat; exergonic refers to free energy
