Answer
See the answer below.
Work Step by Step
The equilibrium constant is the product of the concentration of products, raised to their stoichiometric coefficients, divided by the concentration of reactants, raised to their stoichiometric coefficients, and concentration of solids isn't computed.
a) $K=[O_3]^2/[O_2]^3$
b) $K=[Fe(CO)_5]/[CO]^5$
c) $K=[NH_3]^2[CO_2][H_2O]$
d) $K=[Ag^{2+}]^2[SO_4^{2-}]$
