A reaction 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
