$Δ_{f} G^{-}$ vs $T$ plot in the Ellingham diagram slopes downward for the reaction

Options:

Answer:

Solution:

$C (s) + \frac{1}{2} O_{2} (g) \to CO (g); Δ S$ increases. Hence, as the temperature increases, $T Δ S$ increases and hence $Δ G (Δ H - T Δ S)$ decreases. In other words, the slope of the curve for formation of CO decreases. However, for all other oxides, it increases.
