Comments:
Derived from k(total) and the reported ratio: k(propyne)/k(allene) = (1.92 +/- 0.15)exp[(-177+/-140)/T].
The authors determined temperatures by following the reference reaction 4-methylcyclohexene = 1,3-butadiene + propene. For this reaction they used the rate parameters: k = 1015.3exp(-33,400 K/T) s-1
