... At any given temperature the equilibrium pressure of CO2 (/atm) is equal to the equilibrium constant K and is independent of the relative amounts of CaO and CaCO3 present. K increases with T (=> endothermic reaction) and exceeds 1 at above 1000oC (--> equilm pCO2 > 1 atm). It is then simply necessar ...
