The temperature dependence of absolute rate constans for the F+H2 and F+D2 reactions

Article abstract of DOI:10.1063/1.439818

Multiphoton dissociation of SF6 has been used to generate a transient concentration of fluorine atoms in mixtures with argon and H2 or D2.Absolute rate constans for the F+H2 and F+D2 reactions have been determined as a function of temperature by monitoring the appearance rate of HF or DF product chemiluminescence.In the temperature range from 190 deg K to 373 deg K the results are fit by the expressions k_H=1.0*10^-10 exp(-(860+/-100)/RT) and k_D=9.1*10^-11 exp(-(1100+/-100)/RT), both in cm³ molecule^-1sec^-1.These values are in rough agreement with those obtained recently using a similar technique.The value of the isotope effect k_H/k_D is in good agreement with two previously determined values.
