What is a Limiting Reactant
The reactant that controls the amount of products formed in a chemical reaction and is consumed earlier is called a limiting reactant. In most of the chemical reaction two types of reactant are present.

The limiting reactant is the reagent compound or element to be totally consumed in a chemical reaction.
. The limiting reactant is the one that produces less product and not necessarily the one that is present in fewer amounts. The correct approach is to calculate the moles of both reactants and using molar conversions determine which one produces less produc t.

To take an everyday example 5 buns and 4 hotdogs can. Hence this is called a limiting reactant. To identify the limiting reactant calculate the number of moles of each reactant present and compare this ratio to the mole ratio of the reactants in the balanced chemical equation.
While other reactants may be present in smaller absolute quantities at the time when the last molecule of the limiting reactant is consumed residual amounts of all reactants except the limiting reactant will be present in the reaction. Limiting reactant are those compounds which are totally used up after completion of the chemical reaction and stop any further reaction. The limiting reactant can be.
Limiting reactant is also what prevents a reaction from continuing because there is none left. In a chemical reaction the limiting reactant is the reactant that is consumed first. The limiting reactant may also be referred to as limiting reagent or limiting agent.
One is limiting reactant and another one is excess reagent which left excess after ending the reaction. The limiting reagent or limiting reactant or limiting agent in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. The mass of product.
It controls and limits the amount of product formed. According to the stoichiometry of chemical reactions a fixed amount of reactants is necessary for the reaction to complete. The reactant that is all used up is called the limiting reactant - it sets a limit on how much product can form.
The reactant that is left over is described as being in excess. The limiting reactant or limiting substrate is the reactant present in the smallest stoichiometric amount. This reagent limits the amount of the product generated and the reaction cannot continue without it.
These reagents are a vital part of a chemical reaction while calculating the percentage yield of a given chemical reaction. The reactant that is consumed first and limits the amount of products that can be obtained is the limiting reactant. A limiting reactant is the reactant that is used up first and prevents more product from being made.
Watch the video lecture to better understand about limiting reactant. The limiting reactant is the reactant from which the least amount of product is formed in a chemical reaction Thus the required limiting reagent for the reaction can be recognized using the points mentioned above. The amount of product formed is limited by this reagent since the reaction cannot continue without it.
We know that the Limiting reagents are defined as the substances which are entirely consumed in the completion of a chemical reaction. They are also referred to as limiting reactants or limiting agents. When the limiting reactant is completely consumed the reaction stops and no further product can be made.
The limiting reactant is a reactant or ingredient in a chemical reaction that is exhausted or consumed first for the length the chemical reaction is sustained.
