What does a low K value indicate?

A low equilibrium constant (K) indicates that, at equilibrium:

1. The reaction favors the reactants rather than products.
2. The concentration of reactants is much higher than products.
3. The forward reaction is limited, and only a small amount of reactants is converted into products.

Example:

• In a reaction with K = 0.001, most of the substance remains as reactants at equilibrium.

In simple terms: the lower the K, the more the reaction “leans toward” reactants.
