KINETICS OF CHEMICAL REACTIONS
  • Chemical kinetics, or simply kinetics, is the study of rate of reactions and factors affecting it, like temperature, pressure, catalyst, radiations.
  • On the basis of rate of reaction, reactions can be of slow, moderate and very fast types.
  • Very fast reactions take 10–14 to 10–16seconds for their completion, for example, ionic reactions, such as one shown below

    NaCl + AgNO3 AgCl + NaNO3

  • Fast reactions are not studied under kinetics. ...
