(a) The expression for the equilibrium constant is

K_{c} = \frac{[ NO ] ^{2} [ C l _{2} ]}{[ NOCl ] ^{2}}

.
(b) The expression for the equilibrium constant is

K_{c} = [N O_{2}]^{4} [O_{2}]

.
(c) The expression for the equilibrium constant is

K_{c} = \frac{[ C H _{3} COO H ] [ C _{2} H _{5} O H ]}{[ C H _{3} COO C _{2} H _{5} ]}

.
(d) The expression for the equilibrium constant is

K_{c} = \frac{1}{[ F e ^{3 +} ] [ O H ^{-} ] ^{3}}

.
