Consider the following reaction mechanism: 1) Initiation Br2 → 2 Br• 2) Propagation (here a cycle of two steps) Br• + H2 → HBr + H• H• + Br2 → HBr + Br• 3) Termination 2 Br• → Br2 This reaction is catalyzed by platinum. Wat causes the bromine to split in the initiation step? Does the platinum influences this or is it just due the weak bonding between Br-Br?
