A high equilibrium constant (K) indicates that, at equilibrium:
- The reaction favors the formation of products.
- The concentration of products is much higher than reactants.
- The forward reaction is dominant, and very little reactant remains.
Example:
- In a reaction with K = 10⁶, almost all reactants are converted into products at equilibrium.
In simple terms: the higher the K, the more the reaction “leans toward” products.
Conversely, a low K means the reaction favors reactants.
