The Activity Coefficients of Calcium Carbonate in Alkali Carbonate Melts | Journal of the American Chemical Society RETURN TO ISSUE PREV ArticleNEXT The Equilibrium CaCO3 (melt) =CaO(s) + CO2. Once that partial pressure is reached any change in the amounts of CaO or CaCO3 had no effect on equilibrium. Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. At every temperature the system has a definite partial pressure of CO2. English • You have to login with your ACS ID befor you can login with your Mendeley account. For the following reaction at equilibrium: CaCO3 (s)⇌ CaO (s) + CO2 (g) increasing the total pressure by adding Ar (g) will shift the equilibrium to the right. -CaCO [1(-603.54) + 1(-394.38)] - [1(-1127.8)] = 129.88 kJ 2 CO [1ΔH f (CaO (s)) + 1ΔH f (CO2 (g))] - [1ΔH f (CaCO3 (s aragonite))] [1(-635.13) + 1(-393.51)] - [1(-1207.13)] = 178.49 kJ 178.49 kJ (endothermic) Atomic History • Significant Digits • Atomic Structure • Measurement • -CaO slags for use in hot metal refining.
