Is the following reaction feasible at 400K? Fe2O3 + 3C -> 2Fe + 3CO Enthalpy data: Fe2O3: -822 kJ/mol C: 0 kJ/mol Fe: 0 kJ/mol CO: -111 kJ/mol Entropy data: Fe2CO3: 90 J/K mol C: 6 J/K mol Fe: 27 J/K mol CO: 198 J/K mol A. No, it is not feasible because the Gibbs free energy change is positive. B. No, it is not feasible because the Gibbs free energy change is negative. C. Yes, it is feasible because the Gibbs free energy change is positive. D. Yes, it is feasible because the Gibbs free energy change is negative.
