If Kc is greater than 1, what does that mean?

When the equilibrium constant ( K_c ) is greater than 1, it indicates that at equilibrium, the concentration of products is significantly higher than that of the reactants. This is because ( K_c ) is calculated from the ratio of the concentrations of the products raised to the power of their coefficients to the concentrations of the reactants raised to the power of their coefficients in the balanced chemical equation. A ( K_c ) value greater than 1 suggests that the forward reaction is favored, resulting in a greater amount of products relative to reactants when the system reaches equilibrium.

In summary, a ( K_c ) greater than 1 signifies that the formation of products is favored in the reaction, making option B the correct interpretation.
