Because the simultaneous collision of more than $3$ molecules is statistically very unlikely.

Vedclass · Answer

(B) Molecularity is defined as the number of reacting species (atoms,ions,or molecules) taking part in an elementary reaction,which must collide simultaneously in order to bring about a chemical reaction.For a reaction to occur,these species must collide effectively.The probability of more than $3$ molecules colliding simultaneously is extremely low because it requires a precise orientation and energy alignment for all particles at the same instant.Therefore,reactions with molecularity greater than $3$ are very rare.

Why is the probability of a reaction with molecularity higher than $3$ very rare?
