What are Ellingham's diagrams? Write 2 features of it.
The plots between ΔfGӨ of formation of oxides of elements and temperature are called Ellingham diagrams. It provides a sound idea about selecting a reducing agent in the reduction of oxides. Such diagrams help in predicting the feasibility of a thermal reduction of an ore. ΔG must be negative at a given temperature for a reaction to be feasible.
