Abstract:
We have studied the association reaction of the CF(2)Cl radicals with O(2) in presence of N(2). The infrared multiple photon dissociation (IRMPD) technique with a homemade TEA CO(2) laser was used for the CF(2)Cl radical generation and the vibrational chemiluminiscence technique was set up for the study of the reaction kinetics. The time-resolved IR fluorescence of the vibrationally excited CF(2)O photoproduct was used to measure the disappearance rate of these radicals. A kinetic mechanism is presented to account for the rate of production of CF(2)O(*). The CF(2)Cl radical association reaction rate with O(2), evidence of a direct channel of photoproduct formation and its reaction rate, and the CF(2)O(*) collisional deactivation rate have been obtained.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a reaction.
