1.	Example 2 : If 6 litres of hydrogen and 5-6 litres of chlorine are mixed and exploded,what will be the composition by volume of theresulting gaseous mixture ? Name the limitingreagent.
Answer» ction involved is,H 2 +Cl 2 →2HClmeans 1 mole or 1 LITRE of H 2 needs 1 mole or 1 litre of Cl 2 to react completely and will form 2lit of HCl.Since we have H 2 = 6 litre and Cl 2 = 5.6 litre, so their is Cl 2 present in insufficient amount.Hence, limiting reagent is Cl 2 .So, the REACTION will involved reaction between 5.6 litre of Cl 2 with 5.6 litre of H 2 and 0.4 litre of H 2 will remain unreacted.Hence, 5.6 litre of Cl 2 will produce,5.6×2 = 11.2 litre of HCl.
