CO₂ (g) C(s) + O2(g) Keq = 1 x 10-32 at 1000 K The formation of Fe (s) and O₂(g) from FeO (s) is not thermodynamically favorable

Question

CO₂ (g) C(s) + O2(g)
Keq = 1 x 10-32 at 1000 K
The formation of Fe (s) and O₂(g) from FeO (s) is not thermodynamically favorable at room temperature. In an effort to make the process favorable, C (s) is added to the FeO (s) at elevated temperatures. Base
on the information above, which of the following gives the value of Keq and the sign of AG for the reaction represented by the equation below at 1000 K?
2 FeO (s) + C(s) 2 Fe(s) + CO₂ (g)
