Title: Temperature and pressure dependent rate coefficients for the reaction of Hg with Cl and the reaction of Cl with Cl: A pulsed laser photolysis-pulsed laser induced fluorescence study
Journal: J. Phys. Chem. A
Volume: 109
Page(s): 7732 - 7741
Year: 2005
Reference type: Journal article
Squib: 2005DON/BAU7732-7741
Reaction:
Hg + N2 + Cl → Mercury chloride + N2
Reaction order:
3
Temperature:
243 - 293
K
Pressure: 0.27 - 0.80 bar
Rate expression:
2.2x10-32 [±5.0x10-33 cm6/molecule2 s] e5654 [±3326 J/mole]/RT
Category: Experiment
Data type:
Absolute value measured directly
Pressure dependence:
Rate constant is pressure dependent
Experimental procedure:
Static or low flow - Data taken vs time
Excitation technique:
Flash photolysis (laser or conventional)
Time resolution:
In real time
Analytical technique:
Laser induced fluorescence
Comments:
Hg generated by a mercury permeation tube and elemental mercury and molecular chlorine monitored in situ by UV photometry.
Third-order rate constants calculated by forcing fits through the origin.
The difference between forced and unforced fits varied from 10% for the data at 293 K to 25% at 243 K.
