Which of the following is incorrect on the basic of the above 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))) rarr CO_((g))]`
`lt DeltaS[C_((s))+O_(2(g))rarrCO_(2(g))]`
D. Carbon reduces many oxides at elevated temperature because `Delta_(f) G^(Ө) vs` temperature line has a negative slope.

Answer

C
