Multiple Choice

Express the equilibrium constant for the following reaction:
\quad\quad B(OH) 3(aq) + 2H2O(l) ? B(OH) 3(OH) -(aq) + H3O+(aq)


A) Kc = [H3O+]×[B(OH) 3(OH) −][B(OH) 3]×[H2O]\frac { \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \times \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } ( \mathrm { OH } ) ^ { - } \right] } { \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } \right] \times \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] }
B) Kc = [B(OH) 3]\left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } \right]
[H3O+]×[B(OH) 3(OH) −]\left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \times \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } ( \mathrm { OH } ) ^ { - } \right]

B(OH) 3[H3O+]×[B(OH) 3(OH) −]\frac {B( { OH } ) _ { 3 } } { \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \times \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } ( \mathrm { OH } ) ^ { - } \right]}



C) Kc = [B(OH) 3]×[H2O][H3O+]×[B(OH) 3(OH) −]\frac { \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } \right] \times \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] } { \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \times \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } ( \mathrm { OH } ) ^ { - } \right] }
D) Kc = [H3O+]×[B(OH) 3(OH) −][B(OH) 3]\frac { \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \times \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } ( \mathrm { OH } ) ^ { - } \right] } { \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } \right] }
E) Kc = [B(OH) 3]×[H3O+][B(OH) 3(OH) −]\frac { \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } \right] \times \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] } { \left[ \mathrm { B } ( \mathrm { OH } ) _ { 3 } ( \mathrm { OH } ) ^ { - } \right] }
