Calcination - Wikipedia
In limestone calcination, a decomposition process, the stone reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r = 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.

But in this essay will discuss about decomposition reaction of limestone (CaCO3) become Calcium Oxide and Carbon Dioxide. In a decomposition reaction a more complex substance breaks down into its more simple parts. One reactant yields 2 or more products. For example, limestone can be broken down into carbon dioxide gas and calcium oxide.
What is the thermal decomposition of limestone? | …
Thermal decomposition, or thermolysis, is a stone decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break stone bonds in the compound undergoing decomposition.

Thermal decomposition - Wikipedia
Calcium carbonate (limestone or chalk) decomposes into calcium oxide and carbon dioxide when heated. The stone reaction is as follows: CaCO 3 → CaO + CO 2 The reaction is used to make quick lime, which is an industrially important product. Other example of thermal Decomposition is :- 2Pb(NO 3) 2----> 2PbO + O 2 +4NO 2

What are the products of thermal decomposition? | …
Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.
