The limiting reactant is defined as the reactant that is completely consumed first in a chemical reaction, limiting the amount of product that can be formed. This concept does not depend on the coefficient in the balanced equation, the molar mass of the reactants, or the mass in grams of the reactants alone, but rather on the stoichiometry of the reaction and the initial amounts of the reactants.
