Vedclass · Answer

(B) The thermal decomposition of metal nitrates follows specific patterns based on the reactivity of the metal.$1$. Alkali metal nitrates like $KNO_3$ decompose to form metal nitrites and oxygen gas: $2KNO_3 \xrightarrow{\Delta} 2KNO_2 + O_2$.$2$. Heavy metal nitrates like $AgNO_3$, $Cu(NO_3)_2$, and $Pb(NO_3)_2$ decompose to form metal oxides, nitrogen dioxide $(NO_2)$, and oxygen gas.For example: $2Cu(NO_3)_2 \xrightarrow{\Delta} 2CuO + 4NO_2 + O_2$.Therefore, $KNO_3$ does not produce $NO_2$ upon heating.

$NO_2$ is not obtained on heating:
