The thermodynamic and kinetic studies have been carried out on the reaction of singlet CCl~2 and ozone O~3 at 200K~2000K, using statistic thermodynamic and Eyring transition state theory with Wigner correction on the basis of quantum chemistry. It is concluded that the reaction is thermodynamically favored at low temperatures but kinetically favored at high temperatures.

Key words: OZONE, SINGLET, TRANSITION STATE THEORY
