Solution
Correct Answer:
Proper orientation and sufficient energy
- Collision Frequency: Simply colliding is not enough for a reaction to occur.
- Energy Factor: Colliding particles must have a combined kinetic energy equal to or greater than the threshold energy (or activation energy).
- Orientation Factor: Particles must collide in a specific orientation that allows the redistribution of electrons and breaking/forming of bonds.
- Effective Collisions: Only those collisions that satisfy both the energy and orientation criteria lead to products.
- Theoretical Rate: Rate=P⋅Z⋅e−Ea/RT, where Z is collision frequency and P is the orientation (probability) factor.
This easy difficulty chemistry question is from the chapter chemical kinetics, covering the topic of collision theory. It appeared in the 2025 exam.
