Question

Assertion (A): The order of thermal stability of

\mathrm{Li}_2 \mathrm{CO}_3< \mathrm{Na}_2 \mathrm{CO}_3< \mathrm{K}_2 \mathrm{CO}_3< \mathrm{Rb}_2 \mathrm{CO}_3< \mathrm{Cs}_2 \mathrm{CO}_3

Reason (R): As we go

\mathrm{Li}_2 \mathrm{CO}_3 \rightarrow \mathrm{Na}_2 \mathrm{CO}_3 \rightarrow \mathrm{~K}_2 \mathrm{CO}_3 \rightarrow \mathrm{Rb}_2 \mathrm{CO}_3 \rightarrow \mathrm{Cs}_2 \mathrm{CO}_3

ionic character of carbonates increases.
