What happens during a chemical reaction?
Molecules collide and form or break bonds.
Chemical reactions as we know them are subject to the . According to the collision theory 2 molecules must collide and interact with each other in order to have a reaction.
All chemical reactions are driven by molecule collision, from Glycolysis to mRNA Synthesis.
If there was a specific reaction you had in mind I could go into much greater detail as to the collisions that must take place to complete the reaction.
An example is the formation of ##H_2O## in the following reaction,
##2H^+## + ##O^-2## ##->## ##H_2O##
The reaction shows ##2H^+## ions freely moving about in the environment until they both come in contact with an ##O^-2## ion. are formed and our complete chemical reaction produces water.
