2 FeO(s) ⇌ 2 Fe(s) + O2(g) Keq = 1 × 10−6 at 1000 K CO2(g) ⇌ C(s) + O2(g) Keq = 1 × 10−32 at 1000 K — Equilibrium Chemistry Question

2 FeO(s) ⇌ 2 Fe(s) + O₂(g) Keq = 1 × 10−6 at 1000 K
CO₂(g) ⇌ C(s) + O₂(g) Keq = 1 × 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. Based on the information above, which of the following gives the value of Keq and the sign of ΔG° for the reaction represented by the equation below at 1000 K?

2 FeO(s) + C(s) ⇌ 2 Fe(s) + CO₂(g)
