Calcium Carbonate Decomposes at High Temperatures to Give Calcium Oxide

Question 77

Short Answer

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide.
CaCO3(s) Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide. CaCO<sub>3</sub>(s) CaO(s)+ CO<sub>2</sub>(g) K<sub>P</sub> for this reaction is 1.16 at 800°C. A 5.00 L vessel containing 10.0 g of CaCO<sub>3</sub>(s)was evacuated to remove the air, sealed, and then heated to 800°C. Ignoring the volume occupied by the solid, what will be the overall mass percent of carbon in the solid once equilibrium is reached? CaO(s)+ CO2(g)
