What happens to the limiting reactant in a chemical reaction?

In a chemical reaction the limiting reactant is the reactant that there is the least of in the reaction; it determines the amount of product formed. In a chemical reaction it is the reactant that gets completely "used up"


After a chemical reaction starts when will a chemical reaction end?

When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.


What reactant in a chemical reaction is the limiting reactant?

The term limiting reactant refers to any reactant that is used up first in a chem reaction. (The limiting reactant determines the amount of product that can be formed).


How limiting reactant control a reaction?

The amount of a product of a chemical reaction depends on the amount of the limiting reactant.


Which reactant controls the amount of product formed in a chemical reaction?

The limiting reactant contols the amount of product formed.


In a chemical equation what is the limiting reactant?

determines the amount of product that will form


What is limiting reagent and excess reagent?

limiting reactant/reagent is the reactant/reagent that is in lesser amount in terms of the number of moles. this is the reactant/reagent that determines the theoretical yield of a product(s) in a chemical reaction excess reactant/reagent is the reactant/reagent that is in greater amount in terms of the number of moles.


What is limiting reactant and how control the amount of product formed?

The limiting reactant is that reactant in a chemical reaction that will be used up first. Put another way, it is the reactant that is in the smallest supply. The way it controls the amount of product formed is that once it is used up, no more product can be formed, so the amount of product formed ultimately depends on the amount of the limiting reactant.


Why a limiting reactant controls the amount of product formed in a chemical reaction?

limiting reactant controls the amount of product formed in a chemical reaction because it is found in smaller quantity and consumed earlier .Due to this reason the chemical reaction stops and no additional product is formed


How limiting reactant control the amount of product?

The yield of the reaction depends in this case only on the concentration of the limiting reactant.


Are more product produced at a chemical reaction at equilibrium?

The amount of product is determined by the limiting reactant. Once one reactant is used completely, no more product can be produced.


Why is it necessary to determine if a reactant is a limiting reagent reaction?

The amount of product formed will be limited reagent in a reaction


The amount of product or yield that a reaction is capable of forming is dependent of the quantity of the?

Limiting reactant


Why is limiting reactants important in stoichiometry?

Limiting reactants are the reactants that are used up first. And once they are used up, they stop, or limit, the reaction. So the amount of product that can be produced depends on the limiting reactant. The other reactant, the one in excess, would predict a larger amount of product. But once we produce the amount of product predicted by the limiting reactant. The limiting reactant is used up and the reaction stops.


Why is it necessary to determine if a reactant is a limiting reagent in a reaction?

The amount of product formed will be limited by the amount of the limiting reagent.


Distinguish between limiting reactant and excess reactant in a chemical reaction?

The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.


Why does the amount of product formed is directly proportional to the amount of limiting reactant used?

because the limiting reactant is not in excess so it's all used up . as the limiting reactant is used up the reaction stops so no more product can be made.


What reactant gives the lowest yield by limiting the amount of product?

A reactant that gives the lowest yield by limiting the amount of product is called a limiting reactant. The limiting reactant will run out, so that only a limited amount of product can be made from the reactants.


How does the amount of reactant account for the differences in the rate of reaction?

The more reactant, the faster the reaction The less reactant, the slower the reaction hope that clears it up for you


How is stoichiometry used to calculate amount of product from amount of reactant?

The coefficients give the ratio of moles reactant to moles product.


Why is it necessary to determine if a reactant is limiting reagent in reaction?

The amountof product form will be limited by the amount of the limiting reagent


How is stoichiometry used to calculate the amount of product produced?

Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.


What is the significance of limiting reagent in a chemical process?

limiting reactant controls the amount of product formed in a chemical reaction due to its smaller amount.


What part of chemical equation allows us to determine how much product you can get from a known amount of reactant?

The reaction equation gives the RATIO of moles reactant to moles product. With known molar mass the (mass) yield can be calculated. (Of course other reactants are to be in excess! for complete reaction of the reactant involved for this yield)


Which reactant contorls the amount of product formed in a chemical reaction?

Whichever is the limiting reactant. Let's say you have a chemical equation that is: 3A + 1B --> 1C And you have 3 moles of A and 1000 moles of B. You can only make 3 moles of the product, C because A is the limiting reactant with only three moles. You will have 997 moles of B leftover. The limiting reactant controls the amount of product formed.
