उत्तर
Pb(NO3)2 undergoes a decomposition reaction on heating and produces nitrogen dioxide. It dimerises to give N2O4 gas.
2Pb(NO3)2→ 2PbO+4NO2 +O2
2NO2→N2O4

Assertion: Nitrogen and oxygen are the main components in the atmosphere but these do not react to form oxides of nitrogen.
Reason: The reaction between nitrogen and oxygen requires high temperature.
