The reaction rate varies depending upon what substances are reacting. Acid/base reactions, the formation of salts, and ion exchange are usually fast reactions. When covalent bond formation takes place between the molecules and when large molecules are formed, the reactions tend to be slower. The nature and strength of bonds in reactant molecules greatly influence the r… WebFeb 21, 2012 · Based on real-time kinetic methods for the fast reactions between (iso)flavonoids and radicals of carotenoids, antioxidant synergism during protection of unsaturated lipids has been found to depend on: (i) the appropriate distribution of (iso)flavonoids at water/lipid interface, (ii) the difference between the oxidation potentials …

WebApr 20, 2001 · Abstract. Rapid scavenging of the model stable radical cation, ABTS •+, has been applied to screen for the antioxidant activity of flavonoids. The reaction follows two distinct phases. For compounds with a monophenolic B-ring there is a rapid initial phase of reduction of ABTS •+ within 0.1 s with no further change in the subsequent 2.9 s. WebIn the last module, thermochemistry, we touched on the idea that chemical changes can occur at different rates. They can be fast, like an explosion, or slow, like the rusting of iron.
