According to the collision theory which one of the following statements is correct?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → The colliding molecules should have proper orientation and at least threshold energy for the reaction to occur.
According to collision theory:
- For a reaction to occur, molecules must collide with:
- Proper orientation
- Sufficient energy (equal to or greater than the activation energy)
Other statements are incorrect:
- Energy less than threshold → reaction does not occur
-
Proper orientation alone is not enough. Sufficient energy is also required.
-
Not all collisions are effective. Rate depends on effective collisions, not total collisions.
