Rate constants for the collisional dissociation of N2O5 by N2

Article abstract of DOI:10.1063/1.441055

The rate constants for the collisional dissociation of N2O5 by N2 are measured over the pressure and temperature ranges of 10 to 800 Torr and 285 to 384 K, respectively.The measurements are carried out in flow-through reaction cells of different volumes, the N2O5 being detected by selected ion-molecule reactions in a flowing afterglow apparatus.The present rate constants are somewhat smaller than those of earlier studies and also suggest that the transition from second- to first-order kinetics occurs at lower pressures than was earlier thought.The data are fitted to theoretical models of varying sophistication.The recommended values for use in extrapolation for the limiting low-pressure and high-pressure rate constants corresponding to the first-order Troe extension of the Lindeman-Hinshelwood model for F_cent^SC=0.572 are k₀=1.15*10^-5 exp(-19.70 kcal/mol/RT) cm³ s^-1 and k=1.21*10¹⁷ exp(-25,41 kcal/mol/RT) s^-1.Other forms yield similar results.
