The kinetics of conversion of ozone complexes with a series of substit
uted benzene ArX.O-3 (ArX = C6H5CH, C6H5C2H5, C6H5CH(CH3)(2), C6H5C(CH
3)(3), C6H5F, C6H5Cl, m-BrC6H4CH3, C6H5CH2Cl) have been studied by spe
ctrophotometry. The rate of ArX.O-3 consumption in CH2Cl2-ArX solution
is W=k(0) [ArX.O-3] + k(1) [ArX. O-3] [ArX].
