And that's precisely why the transition state does not exist for a very long time. And in fact, because it doesn't exist for a very long time, it's unstable. And we can't actually study how the transition state looks like. We can't isolate it and we can't examine it because it quickly converts into the products. So the activation energy, delta G with that symbol describes the amount of energy that must be supplied to any reaction in order to actually get it going. Now the activation energy describes how quickly a reaction actually takes place.
