Reaction of earthen oxides to form stable carbonates has been suggested as a potential process for sequestering carbon dioxide. For instance, iron (II) oxide forms iron (II) carbonate: FeO(s) + CO2(g) FeCO3(s) - Using the thermodynamic data in the table provided below, calculate the change in enthalpy for this reaction at 298 K and 500 K. AH (kJ mol-) -393.5 -272.0 -741.0 CO(g) FeO(s) FeCO3(s) Cp.m (J mol- K-) 25.0+ 55.1 x 10-3 x T 68.2 82.8
