Multiple Choice

Write the equilibrium expression for the reaction
Zn²⁺(aq) + 2 NH₃(aq) $\leftrightarrows$ Zn(NH₃) ²⁺(aq)

• A) \(K = \left[ \mathrm { Zn } ^ { 2 + } \right] + 2 \left[ \mathrm { NH } _ { 3 } \right] + \left[ \mathrm { Zn } \left( \mathrm { NH } _ { 3 } \right) ^ { 2 + } \right]\)
• B) \(K = \frac { \left[ \mathrm { Zn } ^ { 2 + } \right] + 2 \left[ \mathrm { NH } _ { 3 } \right] } { \left[ \mathrm { Zn } \left( \mathrm { NH } _ { 3 } \right) ^ { 2 + } \right] }\)
• C) \(K = \frac { \left[ \mathrm { Zn } ^ { 2 + } \right] \left[ \mathrm { NH } _ { 3 } \right] ^ { 2 } } { \left[ \mathrm { Zn } \left( \mathrm { NH } _ { 3 } \right) ^ { 2 + } \right] }\)
• D) \(K = \frac { \left[ \mathrm { Zn } \left( \mathrm { NH } _ { 3 } \right) ^ { 2 + } \right] } { \left[ \mathrm { Zn } ^ { 2 + } \right] \left[ \mathrm { NH } _ { 3 } \right] ^ { 2 } }\)
• E) \(K = \left[ \mathrm { Zn } \left( \mathrm { NH } _ { 3 } \right) ^ { 2 + } \right] - \left[ \mathrm { Zn } ^ { 2 + } \right] - 2 \left[ \mathrm { NH } _ { 3 } \right]\)
