are oxidation reactions exothermic or endothermic?
Endothermic – In thermodynamics, the word Endothermic ‘within-heating’ describes a process or reaction that absorbs energy in the form of heat. Its etymology stems from the Greek prefix endo-, meaning “inside†and the Greek suffix —thermic, meaning “to heatâ€. The opposite of an endothermic process is an exothermic process, one that releases energy in the form of heat. The term “endothermic†was coined by Marcellin Berthelot. The concept is frequently applied in physical sciences to e.g. chemical reactions, where thermal energy (heat) is converted to chemical bond energy. Overview Endothermic, also incorrectly known as endergonic, refers to a chemical reaction in which a system receives heat from the surroundings. Q > 0 When this occurs at constant pressure: ∆H > 0 and constant volume: ∆U > 0 If the surroundings do not supply heat (e.g., when the system is adiabatic), an endothermic transformation….
