Reference type:   Journal article
Squib:   2011LAI/NIC1658-1666

Reaction:   CH2BrCH2Br + ·Cl → Products
Reaction order:   2
Temperature:   244 - 569 K
Pressure:  3.33E-2 - 0.13 bar
Rate expression:   2.84x10-12 [cm3/molecule s] (T/298 K)2.00 e-1530 [J/mole]/RT
Rate constant is an upper limit.
Category:  Experiment
Data type:   Absolute value measured directly
Pressure dependence:   Rate constant is pressure independent
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Resonance fluorescence
Comments:   Contributions to observed kinetics from impurity reactions cannot be ruled out; the quoted modified Arrhenius expression represents the temperature dependence (244-569 K) of upper-limit rate coefficients that are consistentwith the data.
