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.
