GnanasekaranAbstractThe standard molar enthalpies of formation of Bi2Mo3O12 (s), orthorhombic phase of Bi2MoO6 (s), monoclinic phase of Bi2MoO6 (s), Bi6Mo2O15 (s) and Bi6MoO12 (s) were determined by solution calorimetry and the values obtained are (-2915.8 ± 8.2), (-1407.2 ± 7.1), (-1385.7 ± 7.3), (-3346.5 ± 21.7) and (-2605.2 ± 20.3) kJ mol-1, respectively. The given uncertainties were calculated as 2σ of the mean with 0.95 level of confidence.
