Why is the theoretical yield of a reaction determined only by the amount of the limiting reactant?
Because the limiting reactant It is completely consumed before the other reactant.
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.
Which is the limiting reactant when masses of reactants are same?
You must first convert the mass of each reactant into moles of each reactant. Having the same mass does not mean that the amount of each reactant is the same, because each reactant has its own unique molar mass. Refer to the related link below for instructions on determining limiting reactants, also called limiting reagents.
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.
Why does a reaction stop when the limiting reactant is consumed even though there is plenty of the other reactants present?
For a reaction to occur all the reactants are required. If there is no supply of one of the reactants the reaction must stop because there isn't any more of it to keep reacting. When one of the reactants is in low supply or runs out it is called the limiting reactant.
Why is the term limiting used to describe the limiting reactant?
The term "limiting" is used because the limiting reactant limits the amount of product produced.
Why is the theoretical yield of a reaction determined only by the amount of the limiting reactant?
Because the limiting reactant It is completely consumed before the other reactant.
Why concept of limiting reactant is not applied to reversable reactant?
Concept of limiting reactant is not applicable to the reversible reactions because in these reactions all the reactants are converted into products and no reactants remain at the end of the 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.

Examples of How 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

What is the limiting reactant reagent and what is excess reagent in recrystallization?
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.

A solution containing 14 grams of AgNo3 is added to a solution containing 4.83 g of CaCl2. Find the mass of the precipitate produced.?
Ok, lets begin by writing out the reaction : 2AgNO3 +CaCl2 --> 2AgCl(s) + Ca(NO3)2 Precipitate = AgCl Now find the mol of compound in each solution: 14g AgNO3 x (mol/170g) = .082mol 4.83g CaCl2 x (mol/111g) = .044mol Determine limiting reactant: Notice in reaction that 2 CaCl2 molecules react with 1 AgNO3. Because 2(.044mol) > 1(.082mol), AgNO3 is your limiting reactant. Now that you know this you can find the mass of the precipitate .082molAgNO3x (2molAgCl/2molAgNO3)x(143.3g/molAgCl) = 11.75g b) Assuming all the AgNO3 is exhausted, there will be 2(.044)-(.082) = .006mol CaCl2 left .006mol x (111g/mol) = 0.67g CaCl2
What is the limiting reagent in a reaction?
The limiting reagent in a reaction is the reactant that runs out first. For example, if you are reacting 10 moles of HCl and 5 moles of NaOH, you will get 5 moles of H20, 5 moles of NaCl, and 5 moles of HCl, because the remaining HCl had nothing to react with. Therefore, the NaOH is the limiting reagent.
