Question

In the reaction of nitrogen with hydrogen to produce ammonia, NH3, how many moles of ammonia would be produced from 1.0 mol of hydrogen and excess nitrogen?

N2 + 3 H2 --> 2 NH3

0.33 mol
0.67 mol
2.0 mol
1.3 mol

Answer 1

N2 + 3H2 ------> 2NH3
According to the equation;
3 mol of hydrogen will produce 2mol of ammonia.
1 mol of hydrogen _____________________?

= 2 × 1/3

= 0.67 mol

Answer 2

0.67 mol

Step-by-step explanation:

Given data:

Number of moles of ammonia produced = ?

Number of moles of hydrogen = 1.0 mol

Amount of nitrogen = excess

Solution:

Chemical equation:

N₂ + 3H₂ → 2NH₃

Now we will compare the moles of ammonia with hydrogen.

H₂ : NH₃

3 : 2

1.0 : 2/3×1.0 = 0.67

Thus, from 1.0 mole of hydrogen 0.67 moles of ammonia will produced.
