Choose the correct option of temperature at which carbon reduced `FeO` to iron and produces `CO`

Options

A. Below temperature at point A
B. Approximately at the temperature corresponding to point A
C. Above temperature at point A but below temperature at point D
D. Above temperature at point A

Answer

D

Explanation

(d) In the figure shown above point A
`Delta_(r)G_(C,CO)^(@) lt Delta_(f)G_((Fe,FeO))^(@)`
Therefore, above point A , C reduces FeO to Fe forming carbon monoxide Hence, reduction of FeO by carbon occurs above point A only.
