Consider the following reversible chemical reaction at equilibrium:
A(g) + 2B(g) <=> 2C(g)
This reaction has an equilibrium constant, Kc, of 5.0 at a certain temperature. If the initial concentrations of A, B, and C are 1.0 M, 2.0 M, and 0.0 M respectively, what will be the concentrations of A, B, and C at equilibrium?
