Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: pcl₃(g)+cl₂(g)⇌pcl₅(g). a 7.5-l gas vessel is charged with a mixture of pcl₃(g) and cl₂(g), which is allowed to equilibrate at 450 k. at equilibrium the partial pressures of the three gases are ppcl₃ = 0.129 atm, pcl₂ = 0.156 atm, and ppcl₅ = 1.40 atm. what is the value of kp at this temperature? express your answer using three significant figures.
