Starting from conventional macroscopic aspect, the author intends to bridge it to the molecular theory, including The kinetic parameters of the reaction rate are the rate constants k and the orders of the reaction in relation to each component. If a reactant can produce two products, the thermodynamically most stable one will form in general, except in special circumstances when the reaction is said to be under kinetic reaction control.
