Thermodynamic stabilities of SrCeO3 and Sr2CeO4 using the fluoride EMF technique

By combining this expression with the EMF measured using Cell IV, the following expression was obtained for the temperature dependence of the standard Gibbs energy of formation of Sr2CeO4ΔfG∘(Sr2CeO4)±21(kJmol-1)=-2307+0.4400T(K)(805-1066K)
