Chain Reaction Mechanisms

• A chemical pathway characterized by the
  following distinctive steps
• a) Initiatiation
• b) Propagation
• c) Inhibition
• d) Termination

Chain Reaction Mechanisms - contd.

• Initiation A step in which a stable molecular
  species (not necessarily a reactant in the
  overall reaction) reacts to generate one or more
  reactive intermediates
• Propagation A reactive intermediate attacks a
  reactant in the overall reaction to generate a
  new reactive intermediate
• Inhibition A reactive intermediate attacks a
  product in the overall reaction to generate a new
  reactive intermediate
• Termination Reactive intermediates combine with
  one another to form a stable molecular species
