Quizplus · Accepted Answer

The limiting reactant is the one that is completely consumed first in a chemical reaction, limiting the amount of product formed. It is not necessarily the one with the lowest mass, lowest coefficient, lowest molar mass, or the one left over after the reaction. It depends on the stoichiometry of the reaction and the initial amounts of reactants.
