Question

What are the factors that determine an effective collision?

(a) Translational collision and energy of activation

(b) Threshold energy and proper orientation

(c) Proper orientation and steric bulk of the molecule

(d) Collision frequency, threshold energy and proper orientation

The question was posed to me by my college professor while I was bunking the class.

I would like to ask this question from Collision Theory of Chemical Reactions in chapter Chemical Kinetics of Chemistry – Class 12

Answer 1

Right option is (d) Collision frequency, threshold energy and proper orientation

The best explanation: The factors that determine an effective collision are:

Collision frequency: The number of collisions per unit volume of the reaction mixture is known as collision frequency.

Threshold energy: Threshold energy is the minimum kinetic energy the molecules must have to bring about effective collisions between two reactant molecules considered as hard spheres, resulting in a chemical reaction. Proper orientation.
