WebJan 14, 2024 · The rusting of iron or steel is an oxidation reaction -- really just a slower form of combustion. While waiting around for rust to form wouldn't make for an interesting chemistry demonstration, there are ways to speed up the process. For example. you can react steel wool with vinegar in a safe exothermic reaction that evolves heat. WebSep 4, 2024 · The help comes from enzymes. An enzyme is a protein that speeds up a biochemical reaction. It is a biological catalyst. An enzyme generally works by reducing the amount of activation energy needed to start the reaction. Figure 3.10. 2 shows the activation energy needed for glucose to combine with oxygen to produce carbon dioxide …
