Calcination

In limestone calcination, a decomposition process, the chemical 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.
