$LiNO_{3}$

Vedclass · Answer

(D) The thermal decomposition of alkali metal nitrates follows different patterns based on the size of the cation. $LiNO_{3}$ decomposes to form its oxide,nitrogen dioxide,and oxygen: $4LiNO_{3} \rightarrow 2Li_{2}O + 4NO_{2} + O_{2}$. In contrast,nitrates of other alkali metals like $KNO_{3}$,$RbNO_{3}$,and $NaNO_{3}$ decompose to form nitrites and oxygen gas $(2MNO_{3} \rightarrow 2MNO_{2} + O_{2})$ and do not release $NO_{2}$ gas. Therefore,the correct option is $D$.
