Problem 104P

Consider the reaction:

A sample of pure NH4HS is placed in a sealed 2.0-L container and heated to 550 K at which the equilibrium constant is 3.5 × 10‒3. Once the reaction reaches equilibrium, what mass of NH3 is in the container? (Assume that the sample of NH4HS was large enough that equilibrium could be achieved.)

Step-by-Step Solution:

Solution 104P:

Step 1:

The equilibrium constant is

Keq = $\frac{[NH3][H2S]}{[NH4HS(s)]}$ = [NH3][H2S]

Thus, we know that, NH4HS(s) is a solid, so that it is not included into the equilibrium constant.

Keq= 3.5 × 10‒3.

[NH3][H2S] = 3.5 × 10‒3.

From equation, 1 mol NH4HS(s) produces 1.0 mol of NH3(g) and (H2S each.

Thus,

[NH3] = [H2S]

Therefore.

Keq = [NH3][H2S] = [NH3]2

$\Rightarrow{}$ [NH3]2 = 3.5 × 10‒3.

$\Rightarrow{}$ [NH3] = $\sqrt{3.5\ ×\ 10‒3}$ = 0.059 M
