Question
The diffusivity of I, in CCI, is 1.5 x 10 cm's at 320 K. At the same temperature the
rate coefficient for combination of atomic iodine in CCI, was recorded as 7 x 102 cm
mol-s- with a flash method. If the reaction is diffusion controlled, and the diffusivity of
the atom is the same as for the diatomic molecule, do the data give an acceptable model?
The equilibrium nuclear separation of I, is 2.66 x 10-8 cm.
