Chemistry · EQUILIBRIUM

Consider the following statements regarding equilibrium constants: (A) A very large value of \( K_c \) (e.g., \( K_c > 10^3 \)) implies that products predominate over reactants at equilibrium. (B) A very small value of \( K_c \) (e.g., \( K_c < 10^{-3} \)) implies that reactants predominate strongly and the reaction proceeds rarely. (C) If \( K_c \) is between \( 10^{-3} \) and \( 10^3 \), appreciable concentrations of both reactants and products are present. (D) The value of the equilibrium constant \( K_c \) depends directly on the initial concentrations of reactants and products. Which of the above statements are correct?

1. A
   (B), (C) and (D) only
2. B
   (A), (B) and (D) only
3. C

4. D
