Title:   Pressure Dependence of Rate Coefficients for Formation and Dissociation of Pentachlorodisilane and Related Chemical Activation Reactions
Journal:   Int. J. Chem. Kinet.
Volume:   49
Page(s):   584 - 595
Year:   2017
Reference type:   Journal article
Squib:   2017NOD/KUN584-595

Reaction:   SiCl3SiCl: + HClSiCl4 + SiHCl
Reaction order:   2
Temperature:   873 - 1373 K
Pressure:  1.01 bar
Rate expression:   7.36x10-13 [cm3/molecule s] e-54392 [J/mole]/RT
Category:  Theory
Data type:   Transition state theory
Pressure dependence:   Rate constant is pressure dependent
Comments:   Reaction potential energy surface was studied using quantum chemistry and rate constants were calculated for wide ranges of temperatures and pressures (0.1 - 100 atm) using transition state theory, RRKM, and master equation. Rate constants for individual chemically activated channels are presented as a table of Chebyshev polynomial coefficients. Arrhenius equations (quoted here) are given only for two of the channels for the pressure of 1 atm.
