Steady state hot atom kinetic theory model calculations. Time dependent rate coefficients for the nonthermal 18F + H2 reaction

Steady State Kinetic Theory Model Calculations

“…However, recent evidence has shown that Information concerning the energy ränge characteristics of nonthermal reactions is difficuh, if not impossible, to obtain from conventional moderator experiments [14,16,17]. In the present study the influence of Ar additive upon the dynamical and energetic features of the nonthermal + Hj reaction [19][20][21][22][23] has been elucidated with the aid of the steady State kinetic theory of hot atom reactions [21,24,25]. This work represents the first adaptation of the steady State theory for modeling a mukicomponent reaction system.…”

“…Further discussion concerning the limitations of Eq. (1) has been given elsewhere [21,22,25], The time derivative of the total kinetic energy [E^{t)i\ follows from Eq. (1) together with the Boltzmann equation.…”

“…Theoretical reactive cross sections obtained from quasiclassical trajectory caiculations [20] have been utilized in simulations of the nuclear recoil '*F + H^ process [21][22][23]. The computational procedure developed at this laboratory, which has been described in detail elsewhere [21,26], has utilized a local equilibrium Solution of the time dependent Bohzmann equation.…”

Theory of Translational Energy Relaxation in Binary Mixtures of Dilute Gases with Chemical Reaction

“…In Ref. [13] an expression for time derivative of one component's temperature resulting from elastic collisions between non-reactive gaseous components was derived from the Boltzmann equation and compared with the other expressions [15][16][17]. The expressions from Refs.…”

“…[13] and [17] were shown to be equivalent. The other expressions [15,16] have not a form of the relaxation equations in which a difference of temperatures usually appears. It should be emphasized that the expression from Ref.…”
