What does a Keq value greater than 1 imply about a chemical reaction?

A Keq (equilibrium constant) value greater than 1 indicates that at equilibrium, the concentration of products is greater than the concentration of reactants. This is because the equilibrium constant is defined as the ratio of the concentrations of products to reactants, each raised to the power of their stoichiometric coefficients from the balanced reaction equation. When Keq is greater than 1, it shows that the formation of products is favored, meaning that the reaction tends to produce more products before reaching equilibrium compared to the amount of reactants present.

In contrast, a Keq value less than 1 would suggest that the concentration of reactants is greater at equilibrium, while a value equal to 1 indicates that neither reactants nor products are particularly favored, leading to a balance between the two. Thus, a Keq value greater than 1 specifically points to a situation where the forward reaction (reactants converting to products) is favored in producing a higher concentration of products at equilibrium.
