But it needs a boost of energy or heat, like a match, to get it started. Once it catches fire, the log will burn by itself. That extra energy that’s needed to get a reaction started is called the activation energy. It’s a good thing most reactions need activation energy or things would start burning all by themselves! Some reactions are spontaneous. A spontaneous reaction doesn’t need anything to get it started, it just happens. Rust is a good example. As long as all the chemical reactants are present, iron will rust without any activation energy.
