Important Questions on Ellingham Diagrams
Given below are two statements :
Statement I : According to the Ellingham diagram, any metal oxide with higher is more stable than the one with lower .
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.
