Define limiting reagent.5 moles of nitrogen reacts with 5 moles of hydrogen.Find the limiting reagent.
Answers
Answer:
The limiting reagent is the reactant that is used up completely. This stops the reaction and no further products are made. ... One way to determine the limiting reagent is to compare the mole ratios of the amounts of reactants used. This method is most useful when there are only two reactants.First write down, and balance, the chemical equation describing the reaction. Then divide the amount (number of moles) of each reactant by the corresponding stoichiometric coefficient. The lowest of the ratios thus obtained belongs to, and will allow you to recognize, the defective reactant, that is, the reactant that will be completely used up earlier than the others, thus causing the reaction to cease.
In your case, since nitrogen and hydrogen react according to a 1:3 mole ratio, hydrogen will be the defective reactant, present in a smaller amount, from the point of view of the needs of the reaction.
Explanation:
Find the limiting reagent by looking at the number of moles of each reactant.
Determine the balanced chemical equation for the chemical reaction.
Convert all given information into moles (most likely, through the use of molar mass as a conversion factor).
Calculate the mole ratio from the given information.
Answer:
Depends on stoichiometric coefficient.
Explanation:
Just divide the moles by the no. given before(stoichiometric coefficient) both nitrogen and hydrogen and which gives you less no. is the limiting reagent.
