7.21 Equilibrium constant, Kc for the reaction
N2 (g) + 3H2 (g) 2NH3 (g) at 500 K is 0.061
At a particular time, the analysis shows that the composition of the reaction mixture is 3.0 mol L–1 N2, 2.0 mol L–1 H2, and 0.5 mol L–1 NH3. Is the reaction at equilibrium? If not in which direction does the reaction tend to proceed to reach equilibrium?
The given reaction is:
At a particular time
Now we know that,
It is given that
Since , the reaction is not an equilibrium.
Since , the reaction will proceed in the forward direction to reach equilibrium.
