Hint:
Thermal dissociation is defined as the reaction in which a substance undergoes dissociation or in other words breaks-down into simpler substances at high temperatures.

$CaC{O_3}\; \rightleftarrows CaO{\text{ }} + {\text{ }}C{O_2}$
Additional Information: The thermal dissociation is also called as thermal decomposition or thermolysis and there is another term linked to it and that’s decomposition temperature it is the temperature when a substance splits into two or more substances, and the decomposition temperature from the studies is found to be maximum for carbon monoxide at $3870$ degree Celsius, and when water is heated to a temperature of $2000$ degree Celsius, a small percentage of it will decompose into $O{H^ - }$, monatomic oxygen, monatomic hydrogen, ${O_2}$, and ${H_2}$
Note:The energy for $4s$ is less than $3d$ because the overall $\left( {n + l} \right)$ value is less for $4s$ than the $3d$, now the value of $l$ means the value of sub-shells; $s,{\text{ }}p,{\text{ }}d$and $f$are $0,{\text{ }}1,{\text{ }}2,{\text{ }}3$ respectively and for $4s$ the $\left( {n + l} \right)$ value comes out to be $4 + 0{\text{ }} = {\text{ }}4$ and for $3d$ is $3 + 2{\text{ }} = {\text{ }}5.$
