Passage / Comprehension

For the reduction of FeO at the temperature corresponding to point D , which of the following statements is CORRECT ?

Answer:

Solution:

At point D on the Ellingham diagram, the line for FeO reduction by CO intersects the C/CO/CO₂ stability line, meaning the reaction is at equilibrium.

So,

$Δ G^{\circ} = 0 f orre d u c t i o n o f F e O b y CO$

(A) ✔Correct: $Δ G = 0$ at intersection point

(B), (C), (D) Incorrect because C/O₂ and CO systems have negative $Δ G$ (spontaneous oxidation of carbon) at this temperature.
