The rate of reaction between dilute hydrogen sulfide and ozone in air.

The rate of reaction between dilute hydrogen sulfide and ozone in air was measured. Experimental data were obtained from two tubular, laminar-flow reactors having internal dia. of 3/8 in. and l/4 in. On the basis of these data the following expression was obtained for the rate of generation of sulfur dioxide by the reaction of hydrogen sutide with ozone in the absence of light. dcso, = 22.8exp (-65OO/RT) ~~~~~~~~~~ dt Comparison of data from the two reactors indicated that the reaction was almost totally homogeneous. From the results of previous authors the expression is thought to represent the true stoichiometry adequately under the experimental conditions of the present study.
