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) --> 2cao(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
