### Kinetically and Thermodynamically Controlled

Can someone please explain how you know when a reaction is kinetically or thermodynamically controlled? Also, what does it mean when a reaction is kinetically or thermodynamically trapped?

### Re: Kinetically and Thermodynamically Controlled

Short reaction times usually mean the reaction is kinetically controlled while longer reaction times usually suggest thermodynamic reaction control. A reaction that is thermodynamically favored but doesn't occur spontaneously because of a high activation energy is kinetically trapped.
