Ammonia is made industrially by reacting nitrogen and hydrogen under pressure, at high temperature, and in the presence of a catalyst. The equation isN2(g) + 3H2(g) ------> 2NH3(g). If 4.0 mol of H2 react, how many moles of NH3 will be produced?

Answer:

From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.

Explanation:

Given data:

Number of moles of hydrogen react = 4.0 mol

Number of moles of ammonia produced = ?

Solution:

Chemical equation:

N₂ + 3H₂     →       2NH₃

Now we will compare the moles of hydrogen and ammonia from balance chemical equation.

                          H₂               :              NH₃

                           3                :                2

                           4                :              2/3×4 = 2.67 mol

From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
