Calcination

Limestone Calcination. During the calcination of limestone, it follows a decomposition chemical reaction. CaCO 3 → CaO + CO 2 (g) We can take the standard Gibbs free energy of the reaction as ΔG°r = 177,100 − 158 T (J/mol). Meanwhile, the standard free energy of the reaction = 0 when the temperature is set at 1121 K, or 848 °C.
