During reduction of `ZnO` to `Zn, C` is more efficient than `CO`. The standard free energy of formation of `CO_(2)` from `CO` is always higher than that of `ZnO`.A. If both (A) and ( R) are correct and ( R) is the correct explanation of (A).B. If both (A) and ( R) are correct, but ( R) is not the correct explanation of (A).C. If (A) is correct, but ( R) is incorrect.D. If (A) is incorrect, but ( R) is correct. |

Answer» Correct Answer - B `Delta_(f)G^(Ө)` of `CO_(2)` from `CO` is higher than `Delta_(f) G^(Ө)` of `ZnO`, hence `CO` cannot be used to reduce `ZnO` to `Zn`. |
