Chemistry · EQUILIBRIUM

Consider the following statements about the equilibrium constant (\( K_c \)): (A) The value of \( K_c \) for the reverse reaction is the inverse of the equilibrium constant for the forward reaction. (B) When the coefficients in a balanced equation are multiplied by \( n \), the new equilibrium constant is \( K_c^n \). (C) In writing the expression for \( K_c \), concentrations of pure solids and pure liquids are generally omitted. (D) The value of \( K_c \) depends strongly on the initial amounts of reactants taken. Which of the above statements are correct?

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