COLLISION THEORY OF REACTION RATES
According to this theory, a chemical reaction takes place only by collisions between the reacting molecules. But not all collisions are effective. Only a small fraction of the collisions produce a reaction. The two main conditions for a collision between the reacting molecules to be productive are :
(1) The colliding molecules must possess sufficient kinetic energy to cause a reaction.
(2) The reacting molecules must collide with proper orientation.
Now let us have a closer look at these two postulates of the collision theory.
