WebExample. Write the equilibrium constant, K c, for N 2O 4(g) 2NO 2(g) Law of mass action - The value of the equilibrium constant expression, K c, is constant for a given reaction at equilibrium and at a constant temperature. ⇒ The equilibrium concentrations of reactants and products may vary, but the value for K c remains the same. Other ...
WebChemical equilibria are dynamic processes characterized by constant amounts of reactant and product species. The composition of a reaction mixture may be represented by a mathematical function known as the reaction quotient, Q. For a reaction at equilibrium, the composition is constant, and Q is called the equilibrium constant, K. WebWhat are equilibrium constants? Equilibrium constants (Keq) are a way of the quotient of a reaction which has reached equilibrium. The equilibrium expression allows a …
