Barbara Owens · Answer 1

Q = 0.061 = Kc

Explanation:

Step 1: Data given

Temperature = 500 °C

Kc=0.061

1.14 mol/L N2

5.52 mol/L H2

3.42 mol/L NH3

Step 2: Calculate Q

Q=[products]/[reactants]=[NH3]² / [N2][H2]³

If Qc=Kc then the reaction is at equilibrium.

If Qc
If Qc>Kc then the reaction will shift left to reach equilibrium.

Q = (3.42) ² / (1.14 * 5.52³)

Q = 11.6964/191.744

Q = 0.061

Q = Kc the reaction is at equilibrium.
