A mixture initially contains AA, BB,and CC in the followingconcentrations: [A][A]A_1 =0.550 MM , B_1 = 1.10 MM ,and [C][C]C_1 = 0.400 MM . The followingreaction occurs and equilibrium is established:
A+2B⇌CA+2B⇌C
At equilibrium, [A][A]A_2 =0.390 MM and [C][C]C_2 = 0.560 MM .Calculate the value of the equilibrium constant, KcKcK_c.
Express your answer numerically.
