Answer
a. $K_c = {[ Cl_{2} ]^{ \ }}$
b. $K_c = \frac{[ Cu ]^{ \ }[ Cl ]^{ 4 }}{[ CuCl_{4} ]}$
c. $K_c = \frac{[ O_{2} ]^{ 3 }}{[ O_{3} ]^{ 2 }}$
d. $K_c = \frac{[ Mn^{2+} ][ Cl_{2} ]^{ }}{[ H_{3}O^+ ]^{ 4 }[ Cl^- ]^{ 2 }}$
Work Step by Step
Write the equilibrium constant expression:
- The exponent of each concentration is equal to its balance coefficient.
- Pure solids and liquids do not appear in the equation.
a. $K_c = \frac{[Products]}{[Reactants]} = {[ Cl_{2} ]^{ \ }}$
b. $K_c = \frac{[Products]}{[Reactants]} = \frac{[ Cu ]^{ \ }[ Cl ]^{ 4 }}{[ CuCl_{4} ]}$
c. $K_c = \frac{[Products]}{[Reactants]} = \frac{[ O_{2} ]^{ 3 }}{[ O_{3} ]^{ 2 }}$
d. $K_c = \frac{[Products]}{[Reactants]} = \frac{[ Mn^{2+} ][ Cl_{2} ]^{ }}{[ H_{3}O^+ ]^{ 4 }[ Cl^- ]^{ 2 }}$
