Calcium carbonate can be converted to quick lime by the following reaction:
CaCO3(s) → CaO(s) + CO2(g)
Given that: for CaCO3(s) at 25°C ΔHf° = -1206.9 kJ/mol ΔS° = 92.9 J/mol K,
for CaO(s) ΔHf° = -635.5 kJ/mol ΔS° = 39.8 J/mol K
for CO2(g)) ΔHf° = -393.5 kJ/mol ΔS° = 213.6 J/mol K
Use these data to calculate ΔGo for the reaction.
A) 225.7 kJ/mole B) 130.1 kJ/mole C) -130.1 kJ/mole D) -225.7 kJ/mole E) none of these
