Rate Constants for the Reaction of Ar(+)(2P sub 3/2) with N sub 2 as a Function of N sub 2 Vibrational Temperature and Energy Level
Abstract
Rate constants have been measured for the reaction of Ar(+)(2P sub 3/ 2) with N sub 2 as a function of N sub 2 vibrational temperature for a rotational and translational temperature of 300 K. The rate constants increase from a value of 1.2 x 10(-11) cu cm s(-1) at a N sub 2 vibrational temperature of 300K to 2.0 x 10(-10) cu cm s(-1) at a N sub 2 vibrational temperature of 4700 K. The data are used to derive rate constants for specific vibrational levels. The rates constants for v=0-3 are 1.2 x 10(-11), 3.0 x 10(-10), and 7.6 x 10(-10) cu cm s(-1), respectively. Additionally, the data suggest that the rate constant for v>3 drops from the v=3 value, although this is less certain. The increase in the rate constants with increasing v is postulated to arise from the N sub 2(v) yields N sub 2(+) (v+1) channel becoming less endothermic with increasing v and therefore closer to being resonant. Vibrational energy is found to be more effective at promoting this reaction than are translational or rotational energy.
