Question

Consider the following reaction: I2(g)+H2(g)=2hi(g), If the reaction is at equilibrium, and then the I2(g) present at that point in time is removed, what will happen to the concentrations of H2(g) and HI(g)?????? ---A)---H2(g) will increase, HI(g) will increase -----B)---H2(g) will decrease; HI(g) will decrease -----C)---H2(g) will decrease; HI(g) will increase -----D)---H2(g) will increase; HI(g) will decrease -----E)----The concentrations of H2(g) and HI(g) will remain unchanged ----------------NEXT QUESTION--------------------------------------------------------------------------------------------------------------------------------------- Consider the following reaction: PbBr2(s)=Pb2+(aq)+Br-(aq), Which of the species in the reaction are included in the equilibrium constant expression for the reaction??????---A)---PbBr2(s) only ----B)----Pb2+(aq) only ----C)----Br-(aq) only ----D-----Pb2+(aq) and Br-(aq) ----E)----PbBr2(s), Pb2+(aq) and Br-(aq) ----------------NEXT QUESTION-------------------------------------------------------------------------------------------------------------------------------------- Consider the following reaction: N2 (g) + 3 H2 (g) ? 2 NH3 (g), If at equilibrium [N2] = 0.150 M; [H2] = 0.0050 M; and [NH3] = 0.450 M; what is Kc for this reaction????? ----A)------1.1 x 107 ----B)-------7.2 -----C)------1.4 x 10-4 -----D)-------6.0 x 102 ------E)------3.2 x 10-8 -------------------------NEXT QUESTION---------------------------------------------------------------------------------------------------------------------------------- The following reaction: H2 (g) + I2 (g) ? 2 HI (g), Has an equilibrium constant of 30.5 under certain conditions. If initial concentrations of reactants and product are: [H2] = 0.100 M; [I2] = 0.100 M; and [HI] = 0.250 M, what will be the equilibrium concentration of HI??????????? --------A)------0.224 M --------B)------0.040 M ---------C)-----0.100 M ---------D)------0.450 M ---------E)------0.330 M
