Title:   Molecular Dynamics Study of Combustion Reactions in a Supercritical Environment. Part 2: Boxed MD Study of CO plus OH -> CO2 + H Reaction Kinetics
Journal:   J. Phys. Chem. A
Volume:   122
Page(s):   897 - 908
Year:   2018
Reference type:   Journal article
Squib:   2018PAN/MAS897-908

Reaction:   CO + H2CO2 +
Reaction order:   2
Temperature:   400 - 1600 K
Pressure:  1.01 bar
Rate expression:   8.42x10-10 [±1.23x10-11 cm3/molecule s] (T/298 K)(-0.84±0.01) e-207317 [±4351 J/mole]/RT
Category:  Theory
Data type:   Other theoretical
Pressure dependence:   Rate constant is pressure dependent
Comments:   The reaction was studied using boxed molecular dynamics simulations at QM/MM theory level with periodical boundary conditions. Modified Arrhenius expressions were parameterized in a wide range of pressures (1−1000 atm) and temperatures (400−1600 K). The quoted extression is for 1 atm.
