Higher order (>3) reactions are rare due to:

Higher order (>3) reactions are rare due to:
  1. Loss of active species on collision.
  2. Low probability of simultaneous collision of all the reacting species.
  3. Increase in entropy and activation energy as more molecules are involved.
  4. Shifting of equilibrium towards reactants due to elastic collisions.

Solution

Probability of an event involving more than three molecules in a collision are remote.
