Vapor pressure and thermodynamic properties of binary systems of iron dichloride with cadmium and lead chlorides

On the basis of measured boiling temperatures in the systems FeCl2-CdCl2 and FeCl2-PbCl2 for different pressures dependences of saturated vapour pressure on the solution composition, which are described by the equations lg P=B-A/T, are obtained. Normal temperatures of boiling and enthalpy of evaporation are calculated. On the basis of isotherms of total vapour pressure over solution thermodynamic characteristics are calculated: Gibbs energies entropies, enthalpies and activity of components. In the systems asymmetric deviations are found, their character changing with the temperature change
