Calculating K for Overall Reaction
16. Chemical Equilibrium / Calculating K For Overall Reaction / Problem 1

At 789 K, the equilibria for the following reactions are 
CuS(s) + H2(g) β†’ Cu(s) + H2S(g) Kc = 78.9CS2(g) + H2(g) β†’ CS(g) + H2S(g) Kc = 0.289
Based on the given equilibria, what will be the Kc for CuS (s) + CS (g) β†’ Cu (s) + CS2 (g)?
