At a certain temperature, the reaction 2HF(g) H2(g) + F2(g) has Kc = 1.2 × 10-13. Does this reaction proceed far towards completion when equilibrium is reached? If 0.029 mol HF was placed in a 1.00 L container, and permitted to come to equilibrium, what would be the concentration of H2 and F2 in the container? Concentration of F2 at equilibrium = i M Concentration of H2 at equilibrium = i M

Consider the equilibrium system described by the chemical reaction below. A mixture of gas containing only N₂ and H₂ is reacted in a vessel at high temperature. At equilibrium, the 5.0 M H₂, 8.0 M N₂, and 4.0 M NH 3 are present. Determine the initial concentrations of H₂ and N₂ that were present in the vessel. N₂(g) + 3 H₂(g) = 2 NH3(g) Based on the given values, fill in the ICE table to determine concentrations of all reactants and products. Initial (M) Change (M) Equilibrium (M) -2.0 0 2.0 5.0 -5.0 N₂(g) 8.0 1 6.0 + 4.0 -6.0 3 H₂(g) -4.0 10.0 2 NH3(g) RESET 11.0

Consider the equilibrium reaction: 2SO2(g) + O2(g)---->2SO3(g). You place 1.00 mol/L each of SO2 and O2 in a flask and find that at equilibrium the concentration of SO2 is 0.075 mol/L. What is the equilibrium constant for the reaction of SO2 and O2?

a. Suppose the reaction system CH4 (9) +202 (9) ⇒ CO2 (g) + 2H₂O(1) has already reached equilibrium. The position of the equilibrium was shifted by removing any liquid water from the system. Choose the correct effect on equilibrium (it will shift to the right, will shift to the left, or it will not be affected). O It will shift to the right. O It will shift to the left. O It will not be affected. b. Suppose the reaction system CH4 (9) +202 (9) ⇒ CO2 (g) + 2H₂O(1) has already reached equilibrium. The position of the equilibrium was shifted by adding CO₂ to the system by dropping a chunk of dry ice into the reaction vessel. Choose the correct effect on equilibrium (it will shift to the right, will shift to the left, or it will not be affected). O It will shift to the right. It will shift to the left. O It will not be affected. c. Suppose the reaction system CH4 (g) +20₂ (9) — CO2 (g) + 2H₂O(1) has already reached equilibrium. The position of the equilibrium was shifted by performing the…
