Chemistry · EQUILIBRIUM
हिन्दीConsider 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?
Correct answer · Option 3
(A), (B) and (C) only
Explanation
Statements (A), (B), and (C) are correct. Statement (D) is incorrect because \( K_c \) is independent of the initial concentrations of reactants and products at a given temperature.
