For example, in limestone calcination, a decomposition process, the chemical reaction is CaCO 3 = CaO + CO 2 (g). The standard Gibb's free energy of reaction is approximated as ΔG° r = 177,100 - 158 T (J/mol). [1] The standard free energy of reaction is zero in this case when the temperature, T, is equal to 848°C. In addition, example of how calamine ore or zinc carbonate is converted to ...
