Nitrogen and hydrogen react to form ammonia

Nitrogen and hydrogen gases react to form ammonia gas as follows: N2 (g) + 3H2 (g) ——> 2NH3 (g) At a certain temperature and pressure, 1.5L of N2 reacts with 4.5L of H2. If all the N2 and H2 are consumed, what volume of NH3, at the same temperature and pressure, will be produced?

Answer

2(1.5) L = 3 L
2(1.5) L = 3 L According to the stoichiometric coefficients, 1 mol of nitrogen reacts with 3 moles of hydrogen to form 2 moles of ammonia.

Hence, if nitrogen and hydrogen react in a ratio of 1:3, (say x and 3x, 2x of the product, i.e. ammonia will be formed)

Here, x = 1.5
Hence, Amount of ammonia formed = 3 L
