The Haber process which is used to produce ammonia for fertilizercombines hydrogen and nitrogen under high pressure. The equation is shown below:
N, + 3H. = 2NH
70.2 mol
An industrial chemist mixes 105.3 mol
of H, and 56.2 mol of N. in a Haber
process reactor. How many moles of
ammonia will form?
105.3 mol
56.2 mol
35.1 mol

Number of moles of ammonia formed = 70.2 mol

Explanation:

Given data:

Number of moles of H₂ = 105.3 mol

Number of moles of N₂ = 56.2 mol

Number of moles of ammonia formed = ?

Solution:

N₂ + 3H₂        →      2NH₃

Now we will compare the moles of ammonia with both reactant.

               H₂           :            NH₃

                3             :              2

                105.3       :      2/3×1.05.3 = 70.2 mol

                N₂           :            NH₃

                1              :              2

                56.2        :         2×56.2 = 112.4mol

first one is the correct answer
