Which is the correct equilibrium constant expression for the following reaction? Fe2O3(s)+3H2(g)2Fe(s)+3H2O(g) Kc=[Fe2O3][H2]3/[Fe]2[H2O]3Kc=[H2]/[H2O] Kc=[H2O]3/[H2]3 KC=[Fe]2[H2O]3/[Fe2O3][H2]3 Kc=[Fe][H2O]/[Fe2O3][H2] On analysis, an equilibrium mixture for the reaction 2H2S(g)2H2(g)+S2(g) was found to contain 1.0 mol H2S,4.0molH2, and 0.80 mol S2 in a 4.0L vessel. Calculate the equilibrium constant, Kc, for this reaction. 1.6 3.2 12.8 0.64 0.8 The solubility of silver chloride can be increased by dissolving it in a solution containing ammonia. AgCl(s)Ag+(aq)+Cl(aq)K1=1.61010Ag+(aq)+2NH3(aq)Ag(NH3)2+(aq)K2=1.5107 What is the value of the equilibrium constant for the overall reaction? AgCl(s)+2NH3(aq)Ag(NH3)2+(aq)+Cl(aq)Knet=? 1.5107 2.4103 3.1103 2.31014 2.4107 Consider the two gaseous equilibria: SO2(g)+1/2O2(g)SO3(g)2SO3(g)2SO2(g)+O2(g)K1K2 The values of the equilibrium constants K1 and K2 are related by K2=K12K22=K1K2=1/K12K2=1/K1 none of these. Given the following information: 2A(g)+B(g)A2B(g)Kp12A(g)+C2(g)2CC(g)Kp23/2A2(g)+B(g)+C(g)AC(g)+A2B(g)Kp3 Which relationship represents the equilibrium constant for the reaction: 3A2(g)+3B(g)+2C(g)3A2B(g)+C2(g)Knet=? Knet=Kp1Kp2Kp3Knet=Kp12Kp3/Kp2Knet=Kp1Kp2+2Kp3Knet=Kp1Kp32/Kp2Knet=Kp1Kp2Kp32
