The gas-phase dehydrogenation of cyclopentene to cyclopentadiene catalyzed by iodine in. the range 178-283'C has been found to obey a rate law consistent with the slow rate-determining step, I + c-C5Hs --t HI + c-C5H, , log [ka/(l moleL1 sec-')I = 10.25 \* 0.08 -(12.26 f 0.18)/0, where 0 = 2.303RT i
The unimolecular decomposition of but-1-yne has been investigated over the temperature range of 1052"-1152ยฐK using the technique of very low-pressure pyrolysis (VLPP). The primary process is C-C bond fission yielding methyl and propargyl radicals. Application of RRKM theory shows that the experiment
