Hence inter molecular interactions increases which … WebThermal 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 …
WebWater boiling: The process of boiling water is endothermic. This is mostly because heat must be applied in order for water to boil. Endothermic chemical reactions are those in … WebDec 29, 2024 · The bond breaking is always endothermic. The formation of new bonds is exothermic, so depending on whether the old bonds or the new bonds were stronger, the reaction overall can be either endothermic or exothermic. When somebody says chemical bonds “contain potential energy” it is a HIGHLY misleading statement.
