Chemical Kinetics - Result Question 18
####21. Higher order $(>3)$ reactions are rare due to
(2015 Main)
(a) low probability of simultaneous collision of all the reacting species
(b) increase in entropy and activation energy as more molecules are involved
(c) shifting of equilibrium towards reactants due to elastic collisions
(d) loss of active species on collision
Show Answer
Answer:
Correct Answer: 21. (a)
Solution:
- The main conditions for the occurrence of a reaction is proper orientation and effective collision of the reactants.
Since, the chances of simultaneous collision with proper orientation between two species in high order reactions are very rare, so reaction with order greater than 3 are rare.
