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

Answer 1

The correct option is D Collision frequency, threshold energy and proper orientation

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.
