Which of the following is incorrect on the basis of the given Ellingham diagram for carbon?

Options

A. Up to `710^@C`, the reaction of formation of `CO_2` is energetically more favourable, but above `710^@C` the formation of `CO` is preferred.
B. In principle, carbon can be used to reduce any metal oxide at a sufficiently high temperature.
C. `DeltaS [C_((s)) + 1//2 O_(2(g)) to CO_((g))] lt DeltaS [C_((s)) + O_2 to CO_(2(g))]`
D. Carbon reduces many oxides at elevated temperature because `Delta_f G^(Theta)` vs temperature line has a negative slope.

Answer

C
