Question

difference between photochemical decomposition and thermal decomposition explain with many examples

Answer 1

Let Photochemical decomposition be pcd and Thermal decomposition be td.(Took it like this for briefness.)
PCD 1. The process of decomposition of a material that can be decomposed with the help of photolysis.
TD 1. The process of decomposition of a material that can be decomposed with the help of heat energy.
PCD 2. Examples: (i) $2AgCl_{s}$ ⇒(write sunlight above the arrow) 2Ag+ $Cl_{2}$
(ii) $2AgBr_{s}$ ⇒(write sunlight above the arrow) 2Ag+ $Br_{2}$
(iii) $2AgI_{s}$ ⇒(write sunlight above the arrow) 2Ag+ $I_{2}$
TD2. Examples: (i) $2FeSO_{4} (s)$ ⇒(write heat above the arrow) Fe₂O₃(s) + SO₃ + SO₂
(ii) CaCO₃(s) ⇒ CaO(s) + CO₂(g)
(iii) 2Pb(NO₃)₂(s) ⇒(write heat above the arrow) 2PbO(s) + 4NO₂(g) + O₂(g)
