Which of the following statements about the equilibrium is false? Adding more H_2(g) increases the equilibrium constant. Removing HI as it forms forces the equilibrium to the right. If the pressure on the system is increased by changing the volume, the left side favored. If the system is heated, the right side is favored. This is a heterogeneous equilibrium. The proper K_eq expression is: [H_2][I_2]/[HI] squareroot ([H_2][I_2])/[HI]^2 [HI]/squareroot ([H_2]) [HI]^2/[H_2][I_2] [HI]^2/[H_2]

Which of the following statements is FALSE? When Keq << 1, the reverse reaction is favored and the reactants greatly exceed the products at equilibrium Keq >> 1 implies that the reaction is very fast at producing products When Keq ≈ 1, neither the forward or reverse reaction is strongly favored, and about the same amount of reactants and products exist at equilibrium When Keq >> 1, the forward reaction is favored and products greatly exceed reactants at equilibrium
