Say you have a vacuum (imaginary, of course) with three hydrogen atoms, how do we determine which two will bond and which one will be left out? If the same energy is present (equally) for the entire reaction, is the priority given strictly to the two that are closer to each other?




If the collision has too much energy. or if energy released by the bond formation is not dissipated by photon emission, collision, or vibration energy, then the bond is broken again. Similarly, $\ce{2 H}$ need it too to form $\ce{H2}$.


As a mechanical, everyday analogy, imagine a marble play with frictionless terrain, balls and a round enough hole. If you push a ball, it would not end in the (empty) hole, but will escape on the other side. It has to lose some energy somehow, not to be able to escape.
