Equilibrium Constant

Subject: Chemistry

Book: General Chemistry

The equilibrium constant (K) quantifies the ratio of products to reactants at equilibrium, raised to their stoichiometric coefficients. For a reaction aA + bB ↔ cC + dD, K = [C]^c [D]^d / [A]^a [B]^b. A large K (>1) suggests products are favored, whereas a small K (<1) indicates reactants are favored. K is temperature-dependent; changes in temperature can shift equilibrium and alter the value of K.
