Higher order (> 3) reactions are rare due to:
(1) Low probability of simultaneous collision of all the reacting species
(2) Increase in entropy and activation energy as more molecules are involved
(3) Shifting of equilibrium towards reactants due to elastic collisions
(4) Loss of active species on collision
- Low probability of simultaneous collision of all the reacting species
- Increase in entropy and activation energy as more molecules are involved
- Shifting of equilibrium towards reactants due to elastic collisions
- Loss of active species on collision
Correct answer: Low probability of simultaneous collision of all the reacting species
Solution
Higher order reactions are uncommon because the likelihood of multiple molecules colliding at the exact same time decreases significantly as the number of reactants increases, making such reactions less probable.
