Comments:
Experiments were carried out with the pulsed laser powered homogeneous pyrolysis technique.
The stated value was derived with the comparative rate technique relative to the reaction
iso-C3H7Cl -> CH3CH=CH2 + HCl
using log k(iso-C3H7Cl -> CH3CH=CH2 + HCl)/s-1 = 13.6 - (51.1 kcal mol-1/2.3RT)
The authors do not report the exact temperature range of their experiments. The stated temperature range was derived from the data shown in Figure 7 of the paper and is approximate.
