`DeltaG^(Ө)` vs T plot in Ellingham diagram slopes downward for the reaction .A. `Mg + (1)/(2) O_(2) rarr MgO`B. `2Ag + (1)/(2) O_(2) rarr Ag_(2) O`C. `C + (1)/(2) O_(2) rarr CO`D. `CO + (1)/(2) O_(2) rarr CO_(2)` |

Answer» Correct Answer - C `C(s) + (1)/(2) O_(2(g)) rarr CO_((g)) , Delta S` increase. Hence, as the temperature increases, `T Delta S` increases and hence `Delta G(Delta H - T Delta S)` decreases. In other words. The slope of the curve for formation of `CO` decreases. Howeve, for all other oxides, it increases. |
