Kinetic control

Postby AMahadi » Sat Mar 14, 2020 11:40 am

How does the concept of "kinetic control" or "kinetically controlled reactions" work?

The potential outcome of a reaction is usually influenced by the rate of product formation which are kinetic factors

If a reaction is kinetically controlled, that means generally, the temperature is low so the reaction is not controlled by thermodynamic properties but by the kinetics or by the rate of products that can be formed. On the other hand, if a reaction is thermodynamically controlled, the reaction is controlled by the thermodynamic properties of the reaction, and that generally happens at higher temperatures.

It means even if the reaction is thermodynamically unstable or even stable, the reaction will proceed or exist in the form that is not predicted by thermodynamics but is predicted by kinetics.

The rate of formation is a kinetic factor that controls the potential outcome.

The potential outcome can be controlled by the rate of formation of the product which would be the kinetic factor.

The reaction is controlled by the rate of formation rather than thermodynamics which we learned last quarter.

An example that Lavelle gave in lecture was how carbon in the form of a diamond is not as thermodynamically favored as carbon in the form of graphite; however, because of the large energy barrier between the two forms of carbon, the carbon will likely stay in diamond form as becoming graphite would take a long time and would require a lot of energy. This reaction exemplifies kinetic control because it shows how the kinetic properties of the reaction ultimately determine if and how this reaction will occur rather than the thermodynamic properties
