Areaction is in equilibrium as shown: a + b c +
d. calculate the equilibrium constant if the final concentrations stabilize at: a = 9.60 m b = 10.0 m c = 4.00 m d = 4.00 m 0.167 0.408 2.45 5.99

 The correct answer is option (a) i.e. the equilibrium constant is 0.0167

We know,

The equilibrium constant is kc =  Concentration of product/ concentartion of reactants,

kc = [C][D] / [A][B],

 Now,
 
kc= [4.00]*[4.0] / ( [9.60] * [10.00] ) = 0.166 ≈ 0.167

Thus, the equilibrium constant is 0.0167
