Abstract:
The effect of a microwave discharge on the rae of production of HBr in the H2/Br2 system was found to be similar to that observed for the H2/Cl2 system. The interpretation of a large vibrational enhancement on the X(=Cl, Br) + H2 reactions is in agreement with trajectory calculations for these reactions. The criteria of endothermicity and of activation energy as a measure of the role of internal excitation are examined and shown to be useful under different reaction conditions.
