WebExothermic reactions are chemical reactions that produce heat. In Section II-B of Chapter 3, we defined the heat flow q as negative when heat flows from the system to the surroundings. Thus, exothermic reactions have a negative ΔH of reaction. The word exothermic is derived from exo, the Greek word for outside, and therme, the Greek word … WebJan 14, 2024 · The rusting of steel is an example of an exothermic chemical reaction. The rusting of iron or steel is an oxidation reaction -- really just a slower form of combustion. While waiting around for rust to form wouldn't make for an interesting chemistry demonstration, there are ways to speed up the process.
