The reaction shown below is involved in the refining of iron. (The table that follows provides all of the thermodynamic data you should need for this problem.)

(a) Find ΔH° for the reaction.

(b) ΔS° for the reaction above is 557.98 J/K. Find ΔS° for Fe₂O₃(s).

(c) Calculate ΔG° for the reaction at the standard temperature of 298k. (There are two ways that you could do this.)

(d) At what temperatures would this reaction be spontaneous?
