Abstract
Stoichiometric and equilibrium determinations were made of the thermal decomposition reaction of plutonium hexafluoride at temperatures from 150 to 400 deg . The reaction products under these conditions were gaseous fluorine and solid plutonium tetrafluoride. Below 300 deg , the equilibnium constants (moles PuF/sub 2//moles F/sub 2/) were found to be higher than literature values. The sharp change in the relation between log K and l/T at 308 deg reported previously was not found in the present work. The relation between equilibrium constant and temperature is expressed by the equation log K = -1331/T( deg K) - 0.275. (auth)
