Expert Answer
- Limitations of Ellingham Diagram:
(a) Kinetics of reduction:
- Ellingham diagrams are based on thermodynamic concepts, hence, these diagrams suggest whether the reduction of the given metal oxide with a particular reducing agent is possible or not.
- It does not tell anything about the kinetics of the reduction process.
(b) Reactant/product equilibrium:
- The interpretation of ΔGo is based upon equilibrium constant, K. Thus, it is presumed that the reactants and products are in equilibrium.
- But, this is not always true because the reactant or product may be solid.
