If Kc >> 1,
Correct answer: A. The equilibrium mixture will favor products over reactants
- A. The equilibrium mixture will favor products over reactants
- B. The equilibrium mixture will favor reactants over products
- C. The equilibrium amounts of reactants and products are equal
- D. The reaction is irreversible
Explanation
If Kc >> 1, this means that at equilibrium, the concentration of products is significantly higher than that of reactants. The equilibrium constant (Kc) quantifies the ratio of the concentration of products to reactants at equilibrium. A large Kc value indicates that the reaction strongly favors the formation of products. Thus, the correct answer is that the equilibrium mixture will favor products over reactants. Option B is incorrect because it describes the opposite scenario where Kc would be much less than 1. Option C is incorrect because an equal concentration of reactants and products would suggest a Kc around 1. Option D is incorrect because a large Kc does not imply irreversibility; it only shows a strong tendency towards the formation of products.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
