Calculate the ΔH°_rxn for the Decomposition of Calcium Carbonate to Calcium

question 38

Multiple Choice

Calculate the ΔH°_rxn for the decomposition of calcium carbonate to calcium oxide and carbon dioxide. ΔH°_f [CaCO₃(s) ] = −1206.9 kJ/mol; ΔH°_f [CaO(s) ] = −635.1 kJ/mol;
ΔH°_f [CO₂(g) ] = −393.5 kJ/mol
CaCO₃(s) → CaO(s) + CO₂(g)

• A)−2235.5 kJ
• B)−1448.5 kJ
• C)−178.3 kJ
• D)178.3 kJ
• E)2235.5 kJ
