Title:   Ab initio chemical kinetics for ClO reactions with HOx, ClOx and NOx (x=1, 2): A review
Journal:   Comput. Theor. Chem.
Volume:   965
Page(s):   328 - 339
Year:   2011
Reference type:   Journal article
Squib:   2011ZHU/LIN328-339

Reaction:   ClNO2NO2 + ·Cl
Reaction order:   2
Temperature:   400 - 1500 K
Rate expression:   3.76x1021 [cm3/molecule s] (T/298 K)-6.80 e-153061 [J/mole]/RT
Category:  Theory
Data type:   Transition state theory
Pressure dependence:   Rate constant is low pressure limit
Comments:   Potential energy surfaces for a series of reactions were studied using quantum chemistry. Rate constants were calculated using transition state theory and, for pressure-dependent rate constants, master equation methods. Rate constant expression is stated to be for the low-pressure limit (second order) but the values are appropriate for a first-order reaction in s-1.
