Solid zirconium sulphites

Erdos [62ERD] used a correlation method to predict a value of Af//°(Zr(S03)2, cr, 

Erdos [62ERD2] also estimated a value of (418.3 2.7) J-K -mor for the entropy of Reaction (V.62). Using this value, and the entropies of the elements comprising Zr(S03)2(cr), leads to the selected value  

The Gibbs energy of formation is calculated from the selected enthalpy of formation and the entropy
