Does the theoretical yield depend on the amount of limiting reactant?

Does the theoretical yield depend on the amount of limiting reactant?

The reaction stops when any reactant is completely consumed, limiting the amount of product that can be made. That reactant is called the limiting reactant. The maximum possible amount of product, which is called the theoretical yield, depends on the amount of the limiting reactant.

What is theoretical yield and how does this quantity depend on the limiting reactant?

A theoretical yield fora reaction is the number that you calculate for amount of product formed based on the amount of reactants that you are given. If one remectint is the limiting reactant, the amount of product formed will be determined by the amount of this reactant.

What determines theoretical yield?

Theoretical yield is calculated based on the stoichiometry of the chemical equation. The actual yield is experimentally determined. The percent yield is determined by calculating the ratio of actual yield to theoretical yield.

Which reactant is the limiting reactant?

Summary. The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.

How limiting reactant controls the amount of product formed?

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 amount of product formed is limited by this reagent, since the reaction cannot continue without it.

How do you determine the limiting reactant?


  1. Write the balanced chemical equation.
  2. Convert from mass of reactants and product to moles using molar masses and then use mole ratios to determine which is the limiting reactant.
  3. Calculate the percent yield by dividing the actual yield by the theoretical yield and multiplying by 100.

What makes something a limiting reactant?

Why actual yield is always less than theoretical yield?

Usually, the actual yield is lower than the theoretical yield because few reactions truly proceed to completion (i.e., aren’t 100% efficient) or because not all of the product in a reaction is recovered. It’s also possible for the actual yield to be more than the theoretical yield.

Is limiting reagent and limiting reactant the same?

Is limiting reactant the smaller one?

Yes. It’s called the limiting reactant because it gets used up first in a chemical reaction. This results in the smallest amount of reactant in a chemical equation.

How do you calculate limiting reactant?

Calculate Limiting Reagents. [ Chemical Equations Examples: H 2 + O 2 = H 2O. Na 2 + Cl 2 = NaCl ] Use this limiting reagent calculator to calculate limiting reagent of a reaction. To calculate the limiting reagent, enter an equation of a chemical reaction the reactants and products, along with their coefficients will appear.

How does a limiting reactant affect a reaction?

The presence of a limiting reagent will reduce the amount of products a particular reaction can form. The reactant that acts as a limiting reagent will be consumed first by the reaction, in essence leaving the other reactant(s) in excess. This implies that the amounts of products the reaction forms will depend on the limiting reagent.

What reactant in a chemical reaction is the limiting reactant?

Since the amount of product produced by oxygen is less than that produced by ammonia, oxygen is the limiting reactant and ammonia is in excess. As we can see, the limiting reagent or limiting reactant in a reaction is the reactant that gets completely exhausted and thus prevents the reaction from continuing forward.

Which was the limiting reactant?

Since our value is less than the ideal ratio, the top reactant is the limiting reactant. In our case, the top reactant is the hydrogen. Answer: Hydrogen gas is the limiting reactant. It doesn’t matter which reactant you put on top when you do this type of problem as long as you keep it the same throughout the calculations.
