    Are decomposition reaction endothermic or exothermic? Quora

    Apr 08, 2018· Most decomposition reactions require energy either in the form of heat, light or electricity. Absorption of energy causes the breaking of the bonds present in the reacting substance which decomposes to give the product. If decomposition is sufficiently exothermic, a positive feedback loop is created producing thermal runaway and possibly an explosion.

    with the thermal decomposition characteristics of calcareous material of limestone, decomposition temperature of Ca(OH) 2 in carbide slag is much lower than that of CaCO 3 in limestone. Moreover, according to relevant thermodynamic data, endothermal decomposition of Ca(OH) 2 is 1160 kJ kg1, while the endothermal decomposition of CaCO 3 is 1660 kJ kg1. Therefore, from the decomposition

    Thermal decomposition Wikipedia

    Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. If decomposition is sufficiently exothermic, a positive feedback loop is created .
