HELPP Based on the nature of the reactants, which reaction below will occur at the fastest rate at 84°C ?
1. 2KCIO,() 2KCI(s) + 30,(g)
3. N.(g) + 3H2(g) → 2NH,(g)
7. H(aq) + C, H,O, (aq) » HC, H,O,
8. C(s) + O2(g) → CO
(G)

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph

Areaction in which products can react to re-form reactants is
