Formation of Ozone from Atomic Oxygen at Low Temperatures

摘要

Oxygen was passed through an electrodeless discharge and was condensed, either alone or mixed with diluent gases, at liquid helium temperature. On warming through a temperature range of 13ndash;30deg;K the blue solid deposits became more deeply colored. The amount of ozone formed was determined. It was concluded that ozone was formed upon condensation by the predominant reactions (1) and (2)Oplus;Oequals;O2,Oplus;O2equals;O3.The experimentally observed conversion to ozone of 58 agreed well with that calculated from a rate law withk1/k2=1.3. The activation energy of these reactions was estimated to be less than 1.5 kcal.
