Tell me on the basis of 11 What is limiting reagent??
Answers
The limiting reagent in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete
here is your answer hope it will help you
The reactant which is present in lesser amount is called limiting reagent Limiting reagent limits the participation of other reactant which is in excess in the reaction. Example:50 kg N2 and 10kg H2 are mixed to produce NH3.Find the limiting reagent in the production of ammonia N2 + 3H2 → 2 NH3 convert the amount to moles Moles of N2 = 50000g/28g mol-1 = 1785 mol Moles of H2 = 10000g/2.016 = 4960 mol According to the equation 1 mole of N2 reacts with 3 moles of H2 Hence 1785 mole of N2 will react with 3 X 1785 mol = 5355 moles Here we have 4960 moles of hydrogen. hydrogen present in the lesser amount. hence hydrogen is the limiting reagent.
