37 diagram of exothermic reaction
A chemical reaction that involves the release of energy in the form of heat or light is known as an exothermic reaction. When carbon burns in oxygen to make carbon dioxide, for example, a large amount of heat is produced. C + O2 → CO2 (Carbon) (Oxygen) (Carbon dioxide) In this type of reaction, energy (in the form of heat, sound or light) is released when the reactants break apart. Heat energy can be picked up by the area surrounding the products. This means that there was more energy in reactants than in the products. Endothermic Reaction.
Endothermic and exothermic reactionsPaul Andersen explains how heat can be absorbed in endothermic or released in exothermic reactions. An energy diagram can be used to show energy movements in these reactions and temperature can be used to measure them macroscopically.
Diagram of exothermic reaction
Exothermic reactions are opposed to endothermic reactions which involve the absorption of energy from the surrounding in the form of heat. Exothermic chemical reactions transfer the energy in the surrounding area. In the presence of water, a strong acid will dissociate quickly and release heat, therefore it is an exothermic reaction.
