Which of the following expressions for K is correct for the reaction given below? Al 3+ (aq) + 4 OH - (aq) $\rightleftharpoons$ Al(OH) 4 - (aq)

The equilibrium constant expression for the reaction is the concentration of the products over the concentration of the reactants, each raised to the power of their stoichiometric coefficients. Here, the product is $[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } ]$ and the reactants are $[ \mathrm { Al } ^ { 3 + } ]$ and $[ \mathrm { OH } ^ { - } ]^4$.

C) $K = \frac { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] } { \left[ \mathrm { Al } ^ { 3 + } \right] \left[ \mathrm { OH } ^ { - } \right] }$
D) $K = \frac { \left[ \mathrm { Al } ^ { 3 + } \right] \left[ \mathrm { OH } ^ { - } \right] ^ { 4 } } { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] }$
E) $K = \frac { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] } { \left[ \mathrm { Al } ^ { 3 + } \right] \left[ \mathrm { OH } ^ { - } \right] ^ { 4 } }$
