Is freezing water an exothermic reaction
WebSep 12, 2024 · Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. WebSome examples of exothermic processes are: [4] Combustion of fuels such as wood, coal and oil / petroleum. The thermite reaction [5] The reaction of alkali metals and other …
