WebThe term exothermic was first coined by 19th-century French chemist Marcellin Berthelot. The opposite of an exothermic process is an endothermic process, one that absorbs energy usually in the form of heat. The concept is frequently applied in the physical sciences to chemical reactions where chemical bond energy is converted to thermal … WebAn exothermic reaction is a type of chemical reaction that releases heat to its surroundings, resulting in an increase in temperature of the surroundings. In an exothermic reaction, the energy released when new chemical bonds are formed in the products is greater than the energy required to break the chemical bonds in the reactants. As a result, the reaction … flights to porto de galinhasWebExothermic: Bond-breaking is said to be endothermic because energy is consumed to create bonds and released when bonds are broken.
