In an exothermic reaction, the activation energy (energy needed to start the reaction) is less than the energy that is subsequently released, so there is a net release of energy.

Mar 9, 2016 · An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing …

A chemical reaction is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from the system, the temperature of the surroundings increases.

May 8, 2025 · Exothermic reaction: Releases heat (feels hot). These energy exchanges are part of a broader field known as thermochemistry, which studies the heat involved in chemical and physical …
