Question:
Which of the following statements is incorrect about the collision theory of
chemical reaction?
(i) It considers reacting molecules or atoms to be hard spheres and ignores
their structural features.
(ii) A number of effective collisions determine the rate of reaction.
(iii) The collision of atoms or molecules possessing sufficient threshold energy
results into the product formation.
(iv) Molecules should collide with sufficient threshold energy and proper
orientation for the collision to be effective.
Solution:
Option (iii) The collision of atoms or molecules possessing sufficient threshold energy
results into the product formation is the answer.
