The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out.

How do you determine the limiting agent and excess?

The limiting agent in a chemical reaction is the reactant that is completely consumed first, stopping the reaction. To determine the limiting agent, calculate the amount of product each reactant can produce and identify the one that produces the least amount of product. The other reactant is then in excess.


What is the definetions of limiting reactant in chemistery?

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"


What is the reactant called that gets used up first?

The Limiting Reactant is the reactant that runs out first in a reaction.


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

To determine if a reactant is a limiting reagent in a chemical reaction, you need to compare the mole ratio of the reactants used in the reaction with the stoichiometric coefficients from the balanced chemical equation. First, calculate the moles of each reactant available, then use the stoichiometric ratios to find how much of each reactant is required to fully react with the others. The reactant that runs out first, based on these calculations, is the limiting reagent, as it restricts the amount of product formed.


Define limiting reactant?

In a chemical reaction the limitting reactant is also know as limiting reagent.it is the substance which is totally consumed when the chemical reaction is complete.the reacton can not proceed without it.


How does a limiting reagent affect how much product is formed?

The amount of product will be limited by the number of moles of the limitin... reagent.


In a chemical equation the limiting reactant .?

determines the amount of product that will form


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 is the limiting reactant in c6h6 plus hno3---c6h5no2 plus H2O?

The limiting reactant is the reactant that is completely consumed in a chemical reaction. In this case, you would need to compare the moles of each reactant to see which one is completely used up first. Whichever reactant is present in the lowest stoichiometric amount is the limiting reactant.


How limiting reactant control a reaction?

In a chemical reaction, the limiting reactant determines the amount of product that can be formed. It controls the reaction by being completely consumed, thus stopping the reaction once it is used up. This ensures that the other reactants are not wasted and the reaction proceeds in an efficient manner.


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

The amount of product formed is directly proportional to the amount of limiting reactant used because the limiting reactant determines the maximum amount of product that can be produced in a chemical reaction. Any excess reactant beyond the limiting reactant will not contribute to the formation of additional product. Thus, the amount of product formed is dictated by the amount of limiting reactant available.


What is a limiting agent?

In many chemical reactions, there are two reactants. In nearly every case, one of those two reactants "runs out" first, and at that point, the chemical reaction stops, because in order for it to happen, both reactants must be present to react with each other. As soon as the one reactant runs out, the reaction is over, and you have product(s) and one left over reactant. The reactant that runs out first is the limiting reactant. The leftovers are the excess reactant.
