4. Chemical Equilibrium. Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: PCI,(g) + Cl,(g) = PCl(g). A 7.5-L gas vessel is charged with a mixture of PCI,(g) and Cl,(a), which is allowed to equilibrate at 450 K. At equilibrium the partial pressures of the three gases are Pecı, = 0.124 atm, Pei, = 0.157 atm and PpcI, = 1.30 atm. a. What is the value of Kp at this temperature?

4. Chemical Equilibrium. Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: PCI,(g) + Cl,(g) = PCls(g). A 7.5-L gas vessel is charged with a mixture of PCI,(g) and Cl,(a), which is allowed to equilibrate at 450 K. At equilibrium the partial pressures of the three gases are Peci, = 0.124 atm, Pet, = 0.157 atm and Peci, = 1.30 atm. a. What is the value of Kp at this tenperature?
