MCO 3 xrightarrowΔ MO + CO 2 down the group, stability of carbonate ( uparrow) stability of oxide ( downarrow)

Q. Alkaline earth metal carbonates are decomposed on heating and produce residue. Thermal stability of reactant and residue will be - On moving down the group :-

Increases and decreases respectively

Decreases and increases respectively

Increases and increases

Decreases and decreases

$MC O_{3} Δ MO + C O_{2}$
down the group, stability of carbonate $(↑)$
stability of oxide $(↓)$
