JEE · NEET Previous Year Question

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

Topic: JEE PYQ

Answer: C. Full step-by-step solution below.

A $shifting of equilibrium towards reactants due to elastic collisions$
B $loss of active species on collision$
C $low probability of simultaneous collision of all reacting species$
D $increase in entropy as more molecules are involved.$

Correct answer: C

Solution

(c) : Higher order reactions are rare because there is low probability of simultaneous collisions of all reacting species, so the number of effective collisions becomes very less (negligible).
