question 114

Multiple Choice

Express the equilibrium constant for the following reaction:
$\mathrm { Fe } \left( \mathrm { H } _ { 2 } \mathrm { O } \right) _ { 6 } ^ { 3 + } \underset { ( a q ) } { 3 + } + 6 \mathrm { CN } - ( a q ) = \mathrm { Fe } ( \mathrm { CN } ) _ { 6 } ^ { 3 - } \underset { ( a q ) } { 3 - } + 6 \mathrm { H } _ { 2 } \mathrm { O } ( l )$

• A)K_c = \(\frac { \left[ \mathrm { Fe } ( \mathrm { CN } ) _ { 6 } ^ { 3 - } \right] } { \left[ \mathrm { CN } ^ { - } \right] ^ { 6 } \times \left[ \mathrm { Fe } \left( \mathrm { H } _ { 2 } \mathrm { O } \right) 6 ^ { 3 + } \right] }\)
• B)K_c = \(\frac { \left[ \mathrm { Fe } ( \mathrm { CN } ) _ { 6 } ^ { 3 - } \right] \times \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] ^ { 6 } } { \left[ \mathrm { CN } ^ { - } \right] ^ { 6 } \times \left[ \mathrm { Fe } \left( \mathrm { H } _ { 2 } \mathrm { O } \right) _ { 6 } ^ { 3 + } \right] }\)
