Abstract

The reaction between hydrogen and chlorine shows resemblance to that between hydrogen and bromine but is considerably more complicated, owing to the larger number of elementary processes that play a significant part in it. The reaction scheme proposed for the hydrogen-chlorine reaction differs in several important respects from that for the hydrogen-bromine reaction. The main differences are seen to be (1) the inclusion of the reaction H + HBr → H2 + Br and the exclusion of H + HCl → H2 + Cl, and (2) the different chain-terminating steps, Br + Br → Br2 being assumed for bromine and the three processes H + O2, Cl + O2, and Cl + X in the chlorine reaction. The rather marked difference between the reactions of chlorine, bromine, and iodine with hydrogen is that the hydrogen-iodine reaction is elementary while the others are not.
