Example 1

easy
State the three conditions required for a successful chemical reaction according to collision theory.

Solution

  1. 1
    Condition 1: Reactant particles must collide with each other — no collision means no reaction.
  2. 2
    Condition 2: The collision must have sufficient energy (at least equal to the activation energy EaE_a) to break existing bonds.
  3. 3
    Condition 3: The particles must collide with the correct orientation so that bonds can form between the right atoms.

Answer

Collision + sufficient energy + correct orientation = reaction\text{Collision + sufficient energy + correct orientation = reaction}
Collision theory explains reaction rates at the molecular level. Not all collisions lead to reactions — only those meeting all three criteria are 'effective collisions' that produce products.

About Collision Theory

A model explaining that chemical reactions occur only when reactant particles collide with sufficient kinetic energy (at least equal to the activation energy) and in.
