To identify the limiting reactant in a chemical reaction, you need a balanced equation, or equal amounts of atoms in the reactants and products, as well as the amount of reactants in grams and . However, there are times when you do not have exactly the right amount of each ingredient (reactant). Determine the limiting reactant by considering each reactant as independent and determining how many MOLES of product would be made from its starting amount. The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.
