Activated complex is formed due to________________?

Correct answer: B. Effective collision

  • A. Pressure
  • B. Effective collision
  • C. Ineffective collisions
  • D. Temperature

Explanation

An activated complex forms when reactant particles undergo an effective collision with suitable energy and orientation, allowing them to reach the transition state. Students may choose temperature because increasing temperature produces more energetic collisions, but temperature itself does not form the complex; an effective collision does.
