A chemical thermodynamics review applied to V2O5 chlorination

► A chemical thermodynamics review of V2O5 chlorination based on available thermodynamics data and software. ► Discuss the importance of ΔG° × T plots to study the viability of chlorination reactions. ► Reinforce the relationship between ΔG° × T and predominance diagrams, when plotted with thermodynamic consistency. ► Application of different computational methods with diverse complexity for studying the nature of equilibrium states. ► Speciation calculations to study the effect of temperature, partial pressure of O2 and Cl2 over chemical equilibrium.
