At 850°C, CaCO3 (calcite) undergoes substantial decomposition to yield CaO and CO2. Assuming that the AH values of the reactant and products are the same at 850°C as they are at 25°C, calculate the enthalpy change (in kJ) if 63.7 g of CO2 are produced in the reaction. Be sure your answer has the correct number of significant digits. Note: Reference the Thermodynamic properties of pure substances table for additional information. D EX ol Ar AH kJ X
