JEE MAIN - Chemistry (2015 (Offline) - No. 20)
Higher order (>3) reactions are rare due to
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
low probability of simultaneous collision of all the reacting species
Explanation
Reactions of higher order $$\left( { > 3} \right)$$ are very rate due to very less chances of many molecules to undergo effective collisions.
