Consider the following reaction at `1000^(@)C` (A) `Zn (s) + (1)/(2) O_(2) (g) rarr ZnO(s), Delta G^(Ө) = - 360 kJ mol^(-1)` (B) `C (s) + (1)/(2) O_(2) (g) rarr OO(g), Delta G^(Ө) = - 460 kJ mol^(-1)` Choose the correct statement at `1000^(@)C`A. Zinc can be oxidised by `CO`B. `ZnO` can be reduced by `C`C. `ZnO` can be reduced by `CO`D. None of the above |
|
Answer» Correct Answer - B Because the `DeltaG^(@)` of the formation of `CO` is more negative than that of `ZnO` at `1000^(@)C`. |
