In chemical kinetics, only a small fraction of colliisons lead to reactions. This is because

Options

A. may not be properly oriented to one another and the collosions are very energetic
B. are properly oriented to one another and the collisions are not highly energetic
C. may not be properly oriented to one another and the collisions are not energetic
D. arer properly oriented to one another and the collosions are highly energetic

Answer

C

Explanation

In collision theory, the rate constant for reaction is given as a product of three factors: `(1)` `Z` , the collision frequency, `(2)` `p` , th efraction of collision that occur with the reaction molecules property oriented, and `(3)` `f` , the fraction of collision having energy equal to or greater than the activation energy. Thus,
`k=Zpf`
