## Abstract The kinetics of gasโphase reaction of CH~3~CF~2~I with HI were studied from 496 to 549K and have been shown to be consistent with the following mechanism: equation image A least squares treatment of the data gave where ฮธ = 2.303 __RT__ kcal/mole. The observed activation energy __E__
The kinetics of the gas-phase reaction of 2,2,2-trifluoroethyl iodide with hydrogen iodide has been studied over the temperature range of 525'K to 602ยฐK and a tenfold variation in the ratio of CF3CHtI/HI. The experimental results are in good agreement with the expected free radical-mechanism: An an
## Abstract The rate of the reaction of cyclopentadiene with iodine has been followed spectrophotometrically over the temperature range 171.7ยฐ to 276.5ยฐC. The reaction first proceeds almost to the point of equilibrium with cyclopentadienyl iodide and HI, although the final products are fulvalene an
