Options
- A
- B
- C
- D
Correct answer
A.
Step-by-step solution
The thermal stability of carbonates increases down the group. So, the order of thermal stability of carbonates of alkaline earth metals is
\mathrm{BaCO}}_{3}> \mathrm{CaCO}}_{3}>\mathrm{MgCO}}_{3}> \mathrm{BeCO}}_{3} .
Therefore, is thermodynamically most stable and is least stable.
