A higher value of the equilibrium constant Kc shows that
Correct answer: D. Whenever equilibrium will be achieved, the [product] will be very high
- A. The reaction has not gone to near completion.
- B. The reaction has not yet started.
- C. The reaction has gone to near completion towards left.
- D. Whenever equilibrium will be achieved, the [product] will be very high
Explanation
Option D is correct. Yes, a higher value of equilibrium constant K suggests that the [product] will be very high whenever equilibrium is achieved. The equilibrium constant (K) is a measure of the relative concentrations of the reactants and products at equilibrium. A higher value of K means that the products are more concentrated at equilibrium than the reactants. For example, consider the following reaction: A + B <=> C + D If the equilibrium constant for this reaction is 100, then this means that at equilibrium, the concentration of C and D will be 100 times greater than the concentration of A and B. In other words, if we start with equal concentrations of A and B, then at equilibrium, we will have 99% C and D and only 1% A and B. This is because the equilibrium constant is a measure of the relative rates of the forward and backward reactions. A higher value of K means that the forward reaction is more favored than the backward reaction. This means that more products will be formed at equilibrium.

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.
