Mechanism for N<sub>2</sub>O formation from NO at ambient temperature
Bibliographic record
Abstract
Abstract N 2 O was reported to form in sample containers of flue gases containing NO and SO 2 . This could have significant implications for the evaluation of N 2 O buildup in the atmosphere. Existing models are based either on liquid‐phase reactions, which cannot account for N 2 O formation at low humidity, or on termolecular reactions, which are not likely to occur at low concentrations. In this work, we propose mechanisms for N 2 O formation based on gas‐phase reactions, which address the effect of SO 2 , O 2 , and moisture. Analytical expressions of the formation rate were derived and compared to reported rates, and rate constants were estimated for limiting cases. The current analyses suggest that N 2 O 2 could be an important precursor for N 2 O formation from NO, and the mechanism may be important for N 2 O formation in power‐plant plumes.

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.
