✦ Synopsis

The thermal decomposition of F20 has ken investigated in reactors of hfg, Al and quartz usini: a &tic method.

The temperature was varied between 501 and 583°K and the total pressure between 10 and 750 torr. The reaction is homogweous and at moderate and high pressures essentially of second o&i. In the absence of foreign gases the second order constant increases slowly with decreasing pressure. All added gases increase the reaction rate. The following mechanism explains the results: F20 + F20 =F + FO +F20,

The chain length is rather small at pressures above 10 torr and decreases with increasing pressure and increasing temperature. log kr = 13.89 -(38400 + 500 co1/4.57 T) 1 mole-' see-1 hk2 = 7.71 -(13700 '_ 1000 ~a1/4.57 T) 1 mole-l xc -; . ,
