Question

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

Answer 1

According to the collision theory, the reactions occurs due to the collision of the reactant molecules. ... Due to this very low probability of colliding of molecules, the higher order reactions (>3) are quite rare.

Answer 2

Hey !!

The probability of more than three molecules colliding simultaneously is very small. Hence, possibility of molecularity being three is very low.

Good luck !
