Kinetics and Mechanism of Nitrite Oxidation by HOBr/BrO<sup>-</sup>in Atmospheric Water and Comparison with Oxidation by HOCl/ClO<sup>-</sup>
Bibliographic record
Abstract
The rate of the reaction of nitrite with hypobromite/hypobromous acid was studied over a wide range of H + concentrations (6.5 ≤ − log [H + ] ≤ 10). The kinetics were measured as a function of NO 2 -, H + and total Br(I) ([HOBr] total = [HOBr] + [BrO - ] + [BrNO 2 ]) concentrations. A mechanism is proposed for nitrite oxidation involving the reversible formation of BrNO 2, which is then attacked by NO 2 - to yield N 2 O 4 in the rate-determining step. The second-order rate coefficient k 1 for the latter reaction was determined at different ionic strengths in two aqueous media: NaCl and Na 2 SO 4 . Finally, a quantitative comparison of nitrite oxidation by HOBr/BrO - and HOCl/ClO - is presented.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
