If the chemical reaction is: aA + bB → cC + dD and K is the equilibrium constant. Then what is the equilibrium constant of the reaction naA + nbB → ncC + ndD?

According to the "Law of Chemical Equilibrium," the equilibrium constant is the ratio of the product of the concentration of the products to the product of the concentration of the reactants. Each concentration term raises the stoichiometric coefficient in the balanced chemical equation.
