2A(g) ------> C(g) + D(g) .....(given)
Concentration of A = 0.0824 M ...(given)
Concentration of C = 0.0946 M ....(given)
Concentration of D = 0.652 M ...(given)
Kc =?
Kc = Equilibrium constant in term of molar concentration.
Kc for the above reaction can be written as-
Kc = [C]×[D] /[A]^2
Kc = (0.0946 M × 0.652 M )/ (0.0824 M)^2
= 0.0616 / 0.00678
= 9.085
Hence correct option is (a) & = 9.08.
