### Reactions with Multiple Reactants

Why in the section in the course reader(pg. 69) when discussing finding the mechanisms and profiles of a reaction do we perform the method in which we go through multiple separate steps in which we reduce one of the reactants concentrations to a very small amount?I understand that to see how a reactant is affecting a reaction we need to treat it in a different manner but why when its concentration is comparatively much lower than the other reactants' concentrations does it ultimately determine the rate of the reaction?

By limiting the concentration, we are making that species the limiting reagent, with which its concentration will more or less determine the rate of the reaction.
