Question

Statement-I: According to the Ellingham diagram, any metal oxide with higher $\Delta G$ is more stable than the one with lower $\Delta G^{\circ}$.\ Statement-II: The metal involved in the formation of oxide placed lower in the Ellingham diagram can reduce the oxide of a metal placed higher in the diagram.

Professor PC Thomas Classes · Answer

Statement I is false; a *lower* (more negative) $\Delta G^{\circ}$ indicates greater thermodynamic stability. Statement II is true; metals with lower $\Delta G^{\circ}$ lines have a higher affinity for oxygen and act as reducing agents.
