Abstract
The title reaction is an example of a growing group of reactions which exhibit very strong dependence on ion translational energy and/or internal energy of the reactant species. An extensive investigation of the charge transfer reaction between N2 + and SO2 utilizing a flow drift tube has demonstrated that this reaction system has an extremely strong dependence on translational energy [I]. The rate constant reported by Dotan et al. has a miximum value of 7 × 10-10 cc’s per molecule second at thermal energy, declines sharply to a minimum at 0.5 eV and increases at higher energy. Figure 1 illustrates this kinetic energy dependence.

Thermochemical data used in constructing Figure 2 were taken from J.L. Franklin, J.G. Dillard, H.M. Rosenstock, J.T. Herron, K. Draxl and F.H.

It should be noted, however, that an earlier photoionization study by V.H. Dibeler and S.K. Liston, J. Chem. Phys. 49 (1968) 482 reports the threshold for SO+ formation as 15.81 ± 0.02 eV. Further, Meisels et al. (reference 21) report a threshold of 15.93 eV. These lead to endothermicities of 0.21 and 0.35 eV, respectively, for reaction 2 .
