MCQ
Effective collisions are those in which molecules must:
  • A
    Have energy equal to or greater than the threshold energy
  • B
    Have proper orientation
  • C
    Acquire the energy of activation
  • D
    All of the above
✓

Answer

  1. All of the above

Explanation:

These are the characteristics of effective collisions.

Effective collisions are collision between two reactants with the appropriate orientation & with sufficient energy to overcome the activation energy barrier.

The number of effective collisions increases exponentially with an increase in temperature.
