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.

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.

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 …

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 …

The meaning of EXOTHERMIC is characterized by or formed with evolution of heat. How to use exothermic in a sentence.

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.

Mar 28, 2025 · It all comes down to chemistry – specifically, exothermic and endothermic reactions. These two types of reactions dictate whether heat is released or absorbed.

The breaking of bonds is an endothermic process requiring energy, while the making of bonds is an exothermic process with energy being released. The reaction on the surface is exothermic, so the …

EXOTHERMIC definition: noting or pertaining to a chemical change that is accompanied by a liberation of heat (endothermic ). See examples of exothermic used in a sentence.

If the bonds that are formed hold less energy than the bonds that were originally there, you will get an exothermic reaction. Another way of saying this may be to say that, in the process of a heat …
