Answer» Good aap batao...school ja rahe ho? Dosto ke sath bahot mazza aa raha hoga??? Good morning ? bhai The\xa0reactant\xa0which reacts completely in the reaction is called\xa0limiting reactant\xa0or\xa0limiting reagent. Let us consider the following reaction of formation of ammonia:\xa03H2\xa0+ N2\xa0→ 2NH3In the reaction given above, 3 moles of Hydrogen gas are required to react with 1 mole of\xa0nitrogen gas\xa0to form 2 moles of ammonia. But what if, during the reaction, only 2 moles of hydrogen gas are available along with 1 mole of nitrogen.In that case, the entire quantity of nitrogen cannot be used (because the entirety of nitrogen requires 3 moles of hydrogen gas to react). Hence, the hydrogen gas is limiting the reaction and is therefore called the limiting reagent for this reaction. The reactant in a chemical reaction that limits the amount of product that can be formed. The reaction will stop when all of the limiting reactant is consumed. |
