When 2 liter of nitrogen gas reacts with 6 liters of hydrogen gas at constant temperature and pressure,how many liters of ammonia gas will be produced?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction between nitrogen and hydrogen to produce ammonia is:

N2 + 3H2 → 2NH3

This means that for every 1 mole of nitrogen that reacts, 3 moles of hydrogen are needed to produce 2 moles of ammonia. Therefore, the ratio of volumes of nitrogen to hydrogen to ammonia is 2:6:4 or 1:3:2.

Since we are given the initial volumes of nitrogen and hydrogen, we can use this ratio to find the volume of ammonia produced:

2 L of nitrogen x (2/2+6) = 0.5 L of ammonia
6 L of hydrogen x (2/2+6) = 1.5 L of ammonia

The limiting reactant in this case is nitrogen, since there is only enough nitrogen to react with 1.5 L of hydrogen (half of the amount given). Therefore, the volume of ammonia produced is also 0.5 L.

Therefore, the correct answer is B) 4.
