of reactants. DDT obeyed the rate expression 
++.,2, 
rate = ky [Fe D]° [DDT] 
and k. was found to be ca. 3 x 10/1. 2/migle=/min. (256). 
Amines also are present in all organisms; and the reaction of DDT with 
amines and the decomposition of DDT at room temperature was observed (898). 
DDT + NH, CH. + ° DDE + CH NH, +HC1 
Rate of reaction = k [DDT] [NH,CH4]* 
The relationship of DDT vapor pressure to temperature was determined 
(1615).
