Ans.\xa0\tThermal decomposition reaction (Thermolysis) : Decomposition by Heat{tex}CaCO_{3(s)} \\xrightarrow {Heat} CaO_{(s)} + CO_{2(g)}{/tex}\xa0\tElectrolytic decomposition reaction (Electrolysis) :\xa0Decomposition by Current\xa0\t{tex}2NaCl \\xrightarrow {Electricity}2Na+ Cl_2{/tex}\tPhoto decomposition reaction (Photolysis) :\xa0Decomposition by Light\t{tex}2H_2O_{2(l)} \\xrightarrow {Light} 2H_2O_{(l)} + O_{2(g)}{/tex}
