Which of the following expressions is the correct Ko expression for the following reaction?Al,03(s) + 3H,0(1)- 2Al+ (aq) + 60H (aq)Choose one:O A Kç=[A²+]?[oH]6O B. Kc=[Al,0,][H,0]O C.Kc=[Al,0,][H,0]³3O D.Al,0,Kc

Equilibrium is attained by the reaction when the concentrations of reactants become equal to concentrations of product. The equilibrium constant (KC) is the value that is obtained when the reaction attains equilibrium. It can be calculated by dividing the products of equilibrium concentration of products (each raised to their coefficients) by the equilibrium concentration of reactants (each raised to their coefficients).In the equilibrium constant equation, only the concentrations of gaseous and aqueous species are written. The concentrations of solids and liquids are neglected in the equilibrium constant equation because their concentrations are constant. Thus, [Al2O3] and [H2O] terms are not written in the equation of KC as Al2O3 is in solid form and H2O is in liquid form. Hence, KC of the given reaction is expressed as: KC=Al3+2 OH-6 ANSWER - Option A is correct.
