What type of reaction occurs when lead nitrate decomposes on heating?
Answer and explanation
Correct answer: Thermal decomposition
On heating, lead nitrate breaks down because of heat into lead oxide, nitrogen dioxide, and oxygen: \(2\mathrm{Pb(NO_3)_2} \xrightarrow{\Delta} 2\mathrm{PbO} + 4\mathrm{NO_2} + \mathrm{O_2}\). Therefore, it is thermal decomposition. Photolytic decomposition requires light, whereas electrolytic decomposition requires an electric current.
