A mixture initially contains A, B, and C in the following concentrations: [A] = 0.600 M, [B] = 1.00 M, and [C] = 0.400 M. The following reaction occurs and equilibrium is established:A 2B <-> CAt equilibrium, [A] = 0.420 M and [C] = 0.580 M. Calculate the value of the equilibrium constant, Kc.
Suppose that the molar concentrations for CO and H2 at equilibrium are [CO] = 0.05 M and [H2] = 0.08 M. Use the formula Kc[CO][H2]^2 to calculate the concentration of . Express your answer to one decimal place and include the appropriate units.
