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

Consider the following equilibrium reaction. P4S3(g) + 8O2(g) = P4010(s) + 3SO2(9) AH = -3677 kJ If heat is removed from an equilibrium mixture of P4S3, P4010, O2, and SO2, then O Keq will decrease. the system will remain at equilibrium with no change in concentrations. the system will shift toward reactants to re-achieve equilibrium. O the system will shift toward products to re-achieve equilibrium. more information is needed to determine the effect on the equilibrium.
