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

Options

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

Answer

C

Explanation

`Delta S [ C_(s) + 1//2O_(2(g)) rarr CO_(g)] lt Delta S [C_(s) + O_(2) rarr CO_(2(g))]`
