1) Calcium carbonate decomposes at high temperature to form carbon dioxide and calcium
oxide:
CaCO3 → CO2 + Call
Given that the heat of formation of calcium carbonate is -1207 kJ/mol, the heat of formation
of carbon dioxide is -394 kJ/mol, and the heat of formation of calcium oxide is -635 kJ/mol,
determine the heat of reaction.
