What type of decomposition reaction occurs when lead nitrate, eq ext{Pb(NO}_3 ext{)}_2 , is heated?
Answer and explanation
Correct answer: Thermal decomposition
On heating, lead nitrate breaks down into simpler substances:
eq
2 ext{Pb(NO}_3 ext{)}_2
ightarrow 2 ext{PbO} + 4 ext{NO}_2 + ext{O}_2
. Since this decomposition is caused by heating, it is thermal decomposition. Photolytic decomposition requires light energy, such as the decomposition of silver chloride in sunlight.
