In conversion of limestone to lime
Chemical Thermodynamics. In conversion of limestone to lime, CaCO 3 (s) → CaO (s) + CO 2 (g) The values of ΔH and ΔS are +179.1 kJ/mol and 160.2 J/K respectively at 298 K and 1 bar. Assuming that ΔH and ΔS do not change with temperature, temperature above which conversion of limestone to lime will be spontaneous is. 1200 K.
