Collision Theory: What basic behaviors are required of particles in order to react?

Illustrated in this video are the requirements for 1) particles to collide in order to react, 2) for collisions to have some minimum of speed in order to react, and 3) for collisions to occur at the correct orientation in order to react.

You deserve a lot more fame than you get . Good work .

Very easy and understandable explanation of this theory, thank you. My questions are 1. If the kinetic energy is too high and the Chlorine Molecules impact each-other could it result in a fragmentation of the molecules? And would this disperse nuclear energy almost like fission? And 2 Why is it just Chlorine that can interact this way of colliding and connecting? Wouldn’t this ‘formula’ be applicable to other molecules?

can you please make a video showing me where exactly does the energy come from when a molecule like hidrocarbon breaks/burns also i have a question about iron oxides what happens for this to form does the iron loses its energy or what happens, can the process be reversed if energy is given back ?, and most important of all how can the same atom have different numbers of eletrons on its last valency shell, i was watching a video about lewis structures and in one example f2o3 iron had 3 electrons on its last valency shell and the other one f3o4 one of the irons had only 2 electrons on its valency WTF ? how does that all work, its twisting my mind around
