WebSome chemical reactions are so slow that you can’t observe a change right away (such as the formation of rust on a piece of metal), and others are so fast that you might miss them if you blink (like when a firecracker pops). What kind of things cause chemical reactions? What makes them go fast or slow? WebRusting is a slow reaction. It can take many years for a piece of iron or steel to completely rust away. Burning and explosions are fast reactions. They can take very little time to happen. rate of reaction Measures the amount of product formed in a fixed period of time.
