  1. Teori Laju Reaksi • Teori Tumbukan (COLLISION THEORY) • Teori keadaan transisi Atau (Teori Kompleks Teraktifkan)

  2. COLLISION THEORY • Collision theory states that... • particles must COLLIDE before a reaction can take place • not all collisions lead to a reaction • reactants must possess at least a minimum amount of energy - ACTIVATION ENERGY • plus • particles must approach each other in a certain relative way - the STERIC EFFECT • According to collision theory, to increase the rate of reaction you therefore need... • more frequent collisions increase particle speed or • have more particles present • more successful collisions give particles more energy or • lower the activation energy • Video1 video2

  3. The main features of collision theory are: • molecules are hard spheres, i.e. there are no inter molecular interactions, • vibrational and rotational structures of reactants and products are ignored, • the activated complex plays no part in the theory, and • redistribution of energy on reaction is ignored.

  4. Collision theory • Assumption: Molecules are hard spheres and do not interact with each other • Types of collisions • Collision between similar gas molecules • Collision between different types of gas molecules • Collision between moving and stationary molecules • Collision between moving molecules

  5. Collision between moving and stationary molecules
