Equilibrium 3

hey

A chemist puts 6.0 mol of A and 9.0 mol of B into an evacuated 1.0 L container. The system reaches equilibrium at a certain temperature according to the process outline above. When the system is at equilibrium the chemist determines [C] is 8.0 M. What is the equilibrium constant, Kc, for this process at this temperature? Use ICE Chart.
