Question

The selection of the reducing agent depends on the thermodynamic factor.expalin with example

Answer 1

Answer:

Metal will reduce the oxides of other metals which lie above it in Ellingham diagram as the standard free energy change for combined redox reaction will be negative by an amount equal to the difference in ΔfGo of two metal oxides. Thus, both Al and Zn can reduce FeO to Fe but Fe cannot reduce Al2O3 to Al or ZnO to Zn.
