Chemistry

Phosphorus pentachloride is formed when phosphorustrichloride and chlorine react.

PCl3(g) + Cl2(g) ⇌ PCl5(g)

The equilibrium constant for the reaction is KC =37.8 at 110 °C. If 0.887 mol of phosphorustrichloride is added to 0.550 mol ofchlorine in a 1.02-L reaction vessel at thistemperature, what is the equilibrium concentration (inmol/L) of phosphorus pentachloride?

Report your answer to THREE significant figures.
