Collision theory states that for a chemical reaction to occur the reacting particles must collide with one another. in order for collisions to be successful, reacting particles must collide with sufficient energy and in the correct orientation to produce a temporary intermediate product, the activated complex. energy is the minimum energy required for a successful collision.
a.)activation
b.) collision
c.)kinetic
d.)potential
