Some words on measurement uncertainty

F-combustion values are 24.2 kJ-mol-1 [115, 116], 3% more positive than those obtained by solution calorimetry [117] and again larger than the combined estimated uncertainties. 

Considerable spread is also observed in reported enthalpies of transition in single-component systems. As an example, the reported enthalpy of the first-order transition giving the fast ionic conductor phase of Agl at 420 K are compared in Table 10.5. In general, the agreement between the results obtained by adiabatic or 

The next question is how do the results of calorimetry, electrochemical and vapour pressure methods compare The formation properties of BaZrC 3 have been extensively studied. The directly measured Gibbs energy of the reaction
