Quizplus · Accepted Answer

The equilibrium constant (K) is the ratio of the activities of the products to the activities of the reactants, each raised to its stoichiometric coefficient. When the activities of all reactants and products are equal to 1, the equilibrium constant is equal to 1. This is the definition of the standard state. Therefore, if the equilibrium constant is equal to 1, the reactants and products will be in their standard state at equilibrium.
