Consider the reaction:  Fe2O3(s) + 3H2(g) —–> 2Fe(s) + 3H2O(g)  Use ΔG°f values in Appendix 4 to calculate ΔG° for this reaction.Is this reaction spontaneous under standard conditions at 298 K?  The value of ΔH° for this reaction is 100. kJ. At what temperatures is this reaction spontaneous at standard conditions? Assume that ΔH° and ΔS° do not depend on temperature.
