Answer :
Volume of hydrogen required to produce ammonia = 3*5 = 15L
since, 1 mole of nitrogen reacts with 3 moles of hydrogen to produce ammonia.
Amount of ammonia produced = 2*5 = 10L as 1 mole of nitrogen produces 2 moles of ammonia
since, 1 mole of nitrogen reacts with 3 moles of hydrogen to produce ammonia.
Amount of ammonia produced = 2*5 = 10L as 1 mole of nitrogen produces 2 moles of ammonia
