Phosphorus trichloride (PCl₃) reacts with chlorine gas (Cl₂) to produce phosphorus pentachloride (PCl₅) as per the following reversible gas phase reaction: 

The initial and equilibrium concentrations of phosphorus trichloride are 0.30 mol/ L and 0.15 mol/L respectively, while the initial concentration of chlorine is 0.25 mol/ L. Calculate the equilibrium constant, K_C.
