| Also Known As | Keq, Kc, Equilibrium expression, Mass action expression |
What is Equilibrium Constant?
A dimensionless number (K) that expresses the ratio of products to reactants at equilibrium, with each concentration raised to the power of its stoichiometric coefficient. K > 1 favors products; K < 1 favors reactants. Temperature changes alter the value of K.
