The limiting reactant in a chemical reaction is the substance that is entirely consumed first, limiting the amount of products formed. It determines the maximum yield of the reaction.

The limiting reactant can be identified by comparing the mole ratio of available reactants to the mole ratio in the balanced equation.
Calculating the limiting reactant involves converting masses of reactants to moles and using stoichiometric coefficients.
The reactant that produces the least amount of product is the limiting reactant.
Once the limiting reactant is used up, no further product can form, even if other reactants are still available.
Knowing the limiting reactant allows for accurate calculation of theoretical yield and percent yield.
