Answer : The value of equilibrium constant (K) is, 424.3
Explanation : Given,
Concentration of at equilibrium = 0.067 mol
Concentration of at equilibrium = 0.021 mol
Concentration of at equilibrium = 0.040 mol
The given chemical reaction is:
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
Thus, the value of equilibrium constant (K) is, 424.3
