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 …

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 …

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 …

Jul 30, 2024 · Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively. Photosynthesis is a good example of an endothermic reaction.
