Heating is a major factor for the occurrence of different chemical reactions.

Similarly,

If we heat the white lead nitrate powder ,a brown gas of nitrogen dioxide appears.

This process is known as the thermal decomposition of the lead nitrate.

The chemical equation of this chemical reaction is:

2Pb(NO3)2 -> 2PbO + 4NO2 (brown) + O2.

In this chemical reaction the brown coloured gas is actually the nitrogen dioxide gas. (NO2)
