Abstract

fetched live from OpenAlex

Experiments were conducted in a bubble column to determine the equilibrium constants of reactions between NO and ammoniacal cobalt(II) solutions at temperatures between 298.15 and 310.15 K and pH values from 9.06 to 9.37 under atmospheric pressure. The two reactions are 2Co(NH 3 ) 5 (H 2 O) 2+ + 2NO ⇌ (NH 3 ) 5 Co(N 2 O 2 )Co(NH 3 ) 5 4+ + 2H 2 O and 2Co(NH 3 ) 6 2+ + 2NO ⇌ (NH 3 ) 5 Co(N 2 O 2 )Co(NH 3 ) 5 4+ + 2NH 3, respectively. Their equilibrium constants are calculated on the fraction molar basis. All experimental data fit well to the equations ln K NO 5 = 3598.5(1/ T ) + 16.759 and ln K NO 6 = 1476.4(1/ T ) + 26.597, which give the enthalpy of reactions between NO and penta- and hexaamminecobalt(II) nitrates: Δ r H 5 ° = −29.92kJ·mol –1 and Δ r H 6 ° = −12.27kJ·mol –1 .

Full frame distilled prediction

Teacher imitation

Not 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.
