Ellingham diagrams are a particular graphical form of the principle that the thermodynamic feasibility of a reaction depends on the sign of ΔG, the Gibbs free energy change, which is equal to ΔH − TΔS, where ΔH is the enthalpy change and ΔS is the entropy change. The Ellingham diagram plots the Gibbs free energy change (ΔG) for each oxid… WebNov 26, 2024 · The equilibrium partial pressure is read off at the point where the drawn line crosses the nomographic scale. The scale is simply derived by considering the change in free energy of one mole of ideal gas, from p = 1 atm to p = P. We know that. (25.8.1) Δ G ∘ = R T l n ( p O 2) and using equation 12. (25.8.2) G = G ∘ + R T l n ( p p ∘)
