Determine the enthalpy change for the decomposition of calcium carbonate. CaCO3 (s) --> CaO (s) + CO2 (g) given the thermochemical equations below:
Ca(OH)2 (s) --> CaO (s) + H2O (l) enthalpy reaction = 65.2 kJ/mol
Ca(OH)2 (s) + CO2(g) --> CaCO3 (s) + H2O (l) enthalpy reaction = -113.8 kJ/mol
C(s) + O2 (g) --> CO2 (g) enthalpy of reation = -393.5 kJ/mol
2Ca(s) + O2(g) --> 2 CaO (s) enthalpy of reaction = -1270.2 kJ/mol
a. 1711.7 kJ/mol rxn
b. 441 kJ/mol rxn
c. 179 kJ/mol rxn
d. 48 kJ/mol rxn
e. 345.5 kJ. mol rxn
