Top contributors to the provenance of Δ_fH° of CF2ClBr (g)

The 2 contributors listed below account for 99.9% of the provenance of Δ_fH° of CF2ClBr (g).

Please note: The list is limited to 20 most important contributors or, if less, a number sufficient to account for 90% of the provenance. The Reference acts as a further link to the relevant references and notes for the measurement. The Measured Quantity is normaly given in the original units; in cases where we have reinterpreted the original measurement, the listed value may differ from that given by the authors. The quoted uncertainty is the a priori uncertainty used as input when constructing the initial Thermochemical Network, and corresponds either to the value proposed by the original authors or to our estimate; if an additional multiplier is given in parentheses immediately after the prior uncertainty, it corresponds to the factor by which the prior uncertainty needed to be multiplied during the ATcT analysis in order to make that particular measurement consistent with the prevailing knowledge contained in the Thermochemical Network.

Contribution (%)	TN ID	Reaction	Measured Quantity	Reference
53.5	6219.4	CF2ClBr (g) → C (g) + 2 F (g) + Cl (g) + Br (g)	Δ_rH°(0 K) = 365.48 ± 1.60 kcal/mol	Ruscic G4
46.3	6219.3	CF2ClBr (g) → C (g) + 2 F (g) + Cl (g) + Br (g)	Δ_rH°(0 K) = 367.12 ± 1.72 kcal/mol	Ruscic G3X

Top 10 species with enthalpies of formation correlated to the Δ_fH° of CF2ClBr (g)

Please note: The correlation coefficients are obtained by renormalizing the off-diagonal elements of the covariance matrix by the corresponding variances.
The correlation coefficient is a number from -1 to 1, with 1 representing perfectly correlated species, -1 representing perfectly anti-correlated species, and 0 representing perfectly uncorrelated species.

Formula

The aggregate state is given in parentheses following the formula, such as: g - gas-phase, cr - crystal, l - liquid, etc.

Uncertainties

The listed uncertainties correspond to estimated 95% confidence limits, as customary in thermochemistry (see, for example, Ruscic [5] and Ruscic and Bross[6]).
Note that an uncertainty of ± 0.000 kJ/mol indicates that the estimated uncertainty is < ± 0.000₅ kJ/mol.
