Reed free energy of formation of binary compounds. Rare earth oxides ellingham diagram xls author. The ellingham diagram originally constructed for oxides is a tool to find a variety of thermodynamic data quickly without the need for repetitive calculation.
Reed free energy of formation of binary compounds.
2 extraction of iron. 2xm s o 2 g 2m x o s as is evident from the reaction the gaseous amount of reactant is decreasing from left to right as the product formed is solid metal oxide on the right side. The ellingham curve on the graph actually lies lower than most of the other metals such as iron. The oxygen partial pressure is taken as 1 atmosphere and all of the reactions are normalized to consume one mole of o2.
