Which of the following explains the fact that the reactions of high molecularity are rare?

Options

A. The more the number of colliding particles, the more is their weight and difficult it becomes to cross the barrier
B. The activation energy for many-body collisions becomes very large
C. Many-body collisions have low probability
D. Many body collisions are not energetically favoured

Answer

C

Explanation

High molecularity is not observed because many body collisions are very less probable.
