Question

define Thermal decomposition reaction and Photochemical decomposition reaction

Answer 1

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.

Answer 2

decomposition reaction is carried out by heating it is called thermal decomposition
