A Very Very and Very Chemical Inquiry. How do you explain a chemical reaction in general?
Assume there is a complex molecule A which is composed from Nn(A) nuclei and Ne(A) electrons.
Assume there is another complex molecule B which is composed from Nn(B) nuclei and Ne(B) electrons.
Assume a molecule A and a molecule B are about to collide in a suitable environment.
Assume an appropriate relative attitudes of each molecule at the instance of collision.
Assume that as a result of collision, a chemical reaction will occur and product molecules C and D will be made.
Assume that the reactant molecules A and B, and product molecules C and D are chemically different.
Assume that the chemical skeletons of the reactants and products are different.
Can we know the ultimate causes of the locomotive forces that moved the nuclei and changed the reactant molecular configurations into the product molecular configurations? Can we simulate the reaction process by a computer, that is, can we observe the change in the entire wave function using Schroedinger's time dependent equation from the start till the end? By what forces the nuclei are moved and by what forces are the electrons are rearranged? Should we consider the motions of both of nuclei and electrons simultaneously? Is there a critical relative initial attitude for each of molecule to be able to start the chemical reaction? And why do the product molecules C and D part after the reaction? And is a third reactant or a catalyst necessary?
What I am asking is the ultimate law that governs the motions of the nuclei and the electrons at the instance of chemical reaction, and how does the law works.
How do you explain to answer this general chemical question?
Please listen, this is a comlpletely layman as to the chemistry. So, I will be grateful if you could explain in a so plain fashion that even a laymen can understand easily.
