Question

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

Answer 1

Yes, it is feasible because the Gibbs free energy change is positive.
