1 Collision Theory & Factors Affecting Reaction Rate

2 Kinetic Molecular Theory
The Kinetic Molecular Theory states that: All particles are in constant motion Collisions are happening between Other particles Walls of the container

3 Rate = collision frequency X fraction effective
Collision Theory Not all collisions lead to a reaction, in fact most collisions do not lead to a reaction For a reaction to occur, there must be an effective collision between reactants Correct orientation of molecules Sufficient energy Rate = collision frequency X fraction effective

4 Correct Orientation

5 Correct Orientation

6 Sufficient Energy In most reactions, only a small fraction of the total collisions have sufficient energy to overcome the activation energy (EA) of a reaction Activation energy: the minimum collision energy required for a reaction to occur depends on the kinetic energy of the colliding particles
