Chemical Kinetics z Study of the rates of chemical reactions and the factors that influence the rates. z Collision Theory – Collisions between reacting molecules are necessary before a reaction can occur – Only those collisions having sufficient energy are effective in bringing about a reaction activation energy – Colliding molecules must be properly oriented with respect to one another for the reaction to take placeChemical Kinetics z Study of the rates of chemical reactions and the factors that influence the rates. z Collision Theory – Collisions between reacting molecules are necessary before a reaction can occur – Only those collisions having sufficient energy are effective in bringing about a reaction activation energy – Colliding molecules must be properly oriented with respect to one another for the reaction to take place
