WebI. REACTION ORDER First Order Reaction. The simplest chemical reaction is the one in which reactant A forms product P A P (unimolecular) One can study the course of this reaction by observing the formation of product or the disappearance of reactant. The velocity of a reaction is defined as the increase in product /time d[P] v = ----- dt
