Consider the following reaction: A(g)= B(g)+C(g) Find the equilibrium concentrations of A, B, and C for each of the following different values of Kc. Assume that the initial concentration of A in each case is 1.0 M and that the reaction mixture initially contains no products. Make any apprpiate simplifying assumptions. 1) Kc=2.0 2)Kc=1.6*10^-2 3)Kc=2.0*10^-5
