Abstract

fetched live from OpenAlex

The oscillatory reaction of potassium bromate, oxalic acid, and MnSO 4 in the presence of acetone in aq H 2 SO 4 solutions has been studied calorimetrically at different concentrations of substrates. Acetone and oxalic acid have been found to accelerate the reaction by increasing the oscillation frequency. On the other hand, MnSO 4 has a retarding effect; the frequency of oscillation decreases systematically with increasing concentration of MnSO 4 . Potassium bromate shows mixed behavior in this respect. The total heat evolved during the reaction per mol of oxalic acid consumed has been evaluated, which can be used to calculate the concentrations of the various reactants at different stages of the reaction. The effects of different electrolytes (KCl, NaCl, BaCl 2 , CaCl 2 , SrCl 2 , NaBr, NaI, KNO 3 , NaNO 3 , and Ca(NO 3 ) 2 ) and solvents (dimethylformamide, 1,4-dioxane, acetonitrile, and tetrahydrofuran) on the extents of oscillation and the enthalpy change for the process have been also examined.Key words: Belousov–Zhabotinsky reaction, oscillatory reaction, oxalic acid, calorimetry, acetone.

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.
