Phosphorus pentachloride is formed when phosphorus trichloride and chlorine react. PCl3(g) + Cl2(g) ⇌ PCl5(g) The equilibrium constant for the reaction is KC = 38.0 at 233 °C. If 0.510 mol of phosphorus trichloride is added to 0.238 mol of chlorine in a 1.11-L reaction vessel at this temperature, what is the equilibrium concentration (in mol/L) of phosphorus pentachloride? Report your answer to THREE significant figures.

a.) Calculate the partial pressure in bar of phosphorus pentachloride produced in a system in which phosphorus trichloride and chlorine gases are initially each at a partial pressure of 3.00 bar and allowed to reach equilibrium. The reaction is run at a temperature in which the equilibrium constant = 1.12. Note: This K value is for the reaction written as: PCl3(g) + Cl2(g) ----> PCl5(g) b.) Strontium-90 is a radionuclide that is a legacy of nuclear weapons development and testing....
