A reaction of A produces two products, C and D , according to:A (aq) 2C(aq) + D(aq) When A is placed in the flask, its concentration is 0.050 M. The equilibrium concentration of A is measured to be 0.040 M. What is the equilibrium constant for this reaction?Hint:K = [C]2[D][A], Construct the ICE table :
