Abstract
The gas-phase decomposition
of ethyl bromide at 423� in the presence of both ethylene and hydrogen bromide
has been investigated. These additives, which are also the products, each
influence the rate strongly but in opposite ways. The variation of initial rate
with reactant pressure is given by (P in cm)
������������� k1 (min-1)
= 15.2x10-3+19.5x10-3(PEtBrPHBr/PEne)1/2
This has been interpreted
in terms of a unimolecular decomposition together with a bromine atom carried
chain reaction with simple steps that involve the products. Some insight into
the unaccompanied decomposition has been gained. Some remarks about the role of
olefinic inhibitors in reactions producing hydrogen bromide have been made.
