Reference type:   Journal article
Squib:   2012REN/DAV423-432

Reaction:   C2H4C2H2 + H2
Reaction order:   2
Temperature:   1519 - 1895 K
Pressure:  2.05E-5 - 2.85E-5 bar
Rate expression:   4.33x10-8 [cm3/molecule s] e-283773 [J/mole]/RT
Category:  Experiment
Data type:   Absolute value measured directly
Pressure dependence:   Rate constant is low pressure limit
Experimental procedure:   Flow tube - Data taken vs distance
Excitation technique:   Thermal
Time resolution:   In real time
Analytical technique:   IR absorption
Comments:   The primary contributions to uncertainties in the rate coefficients are: temperature (1%), fitting the data to computed profiles (5%), and C2H4 cross section (5%). These uncertainties give overall uncertainties in the rate constant of 20%.
