In the present paper, thermodynamic properties of compounds of ZnO-V₂O₅ system have been reported. Phase pure compounds of ZnO-V₂O₅ system viz., ZnV₂O₆, Zn₂V₂O₇, Zn₃V₂O₈ and Zn₄V₂O₉ have been prepared and characterized. The standard molar enthalpies of formation of these compounds at 298 K (${∆}_f{H}_{298}^o$) and their isobaric heat capacity were determined employing calorimetric techniques. From their enthalpy of formation and the temperature dependent molar heat capacity data, thermodynamic functions of ZnV₂O₆(s), Zn₂V₂O₇(s), Zn₃V₂O₈(s) and Zn₄V₂O₉(s) compounds have been derived. From these derived thermodynamic parameters, the relative stabilities of the compounds were determined.
