What is kinetic control and how does It relate to kinetics?

There is thermodynamic control and kinetic control. These deal with the composition of a reaction, in regards to products and reactants. Professor Lavelle went touched over this when we talked about C(Diamond) -> C(Graphite). This reaction is not thermodynamically favored, but is kinetically favored, therefore, this reaction is under kinetic control. There are examples of the opposite, which you can find online. This is related to kinetics beacuse it simply deals with the rates of these reactant to product transformations, in the example of diamond to graphite this rate is extremely slow.

In principle, every reaction is on the continuum between pure kinetic control and pure thermodynamic control. These terms are with respect to a given temperature and time scale. A process approaches pure kinetic control at low temperature and short reaction time. At the other end of the continuum, thermodynamic control is approached with a sufficiently long time scale and high temperature.
