Answer

$Kc = \frac{P[O_{2}]^3}{P[O_{3}]^2}$ homogeneous

Work Step by Step

The expression of Kc is the concentration of the products raised to their coefficients divided by the concentration of the reactants raised to their coefficients. $Kc = \frac{[O_{2}]^3}{[O_{3}]^2}$ Since we have gases and not aqueous solutions, we have partial pressures and not concentration so we have: Both reactants and products are gases so it is homogeneous $Kc = \frac{P[O_{2}]^3}{P[O_{3}]^2}$
