Question: Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity
Answer: (a) Thermal Decomposition
2FeSO₄(s) + Heat ⟶ Fe₂O₃(s) +SO₂(g)+SO₃(g)
(b) Decomposition by light:
2AgCl(s) + Light ⟶ 2Ag(s)+Cl(g)
(c) Decomposition by electricity:
2Al₂O₃(aq) + Electricity ⟶ 4Al(s) + 3O₂(g)
