The reaction for the Haber process is
N2 + 3 H2 ⇌ 2 NH3
Amount of N2 = 3.41/28.0 = 0.122mol
Amount of H2 = 2.79/2.0 = 1.40mol
According to the stoichiometry of the reaction, 1 mol of N2 reacts with 3 mol of H2. 0.122mol of N2 will therefore react with only 0.366mol of H2, but there is 1.40mol of H2 available. Thus H2 is in excess and N2 is the limiting reactant.
1mol of N2 reacts to form 2 mol of NH3.
Under the maximum possible yield, 0.122mol of N2 reacts to form 0.244mol of NH3.
Mass of NH3 = 0.244 x 17.0 = 4.15g

What is the limiting reactant when 3.14g of nitrogen react with 2.79g of hydrogen to produce ammonia and how many grams of ammonia are produce?
Nitrogen is the limiting reactant and 4.15g of ammonia are produced.
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.
Why concept of limiting reactant is not applied to reversible reaction?
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.
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.
If 100 g of CuS and 56 g of O2 are available which is the limiting reactant?
Cus
What is the limiting reactant when 3.14g of nitrogen react with 2.79g of hydrogen to produce ammonia and how many grams of ammonia are produce?
Nitrogen is the limiting reactant and 4.15g of ammonia are produced.
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.
What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
How do you find out how many moles of lead will be produced from a limiting reactant?
Knowing the limiting reactant, ignore other reactants and calculate the product (lead) based on just that one reactant using the coefficients of the balanced equation.
What mass of ammonia NH3 could be produced from the reaction of 44.5 g of nitrogen N2 and 2.58 g of hydrogen H2?
The equation for the reaction is N2 + 3 H2 -> 2 NH3. The gram atomic mass of nitrogen is 14.0067, and the gram atomic mass of hydrogen is 1.00794. Therefore, the mass fraction of nitrogen in ammonia is 14.0067/[14.0067 + (3*)(1.00794)] or about 0.8225, and, since nitrogen and hydrogen are the only two elements present, the mass fraction of hydrogen is 1*- 0.8225 or about 0.1775. The mass fraction of nitrogen in the amounts of nitrogen and hydrogen specified is 44.5/(44.5 + 2.58) or about 0.945. Therefore, hydrogen is the limiting reactant in this mixture, and the mass of ammonia produced is 2.58/0.1775 or 14.5 grams, to the justified number of significant digits. ________________ *An exact integer.
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 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.
What is the limiting reactant in alka-seltzer?
Sodium bicarbonate is the limiting reactant.
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 limiting reactant control a reaction?
Using an excess of another reactant limits a reactant.
What is the reactant that runs first out in a reaction called?
The Limiting Reactant is the reactant that runs out first in a reaction.
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"
