02:18The equilibrium 2 NO(π) + Cl2(π) β 2 NOCl(π) is established at 500.0 K. An equilibrium mixture of the three gases has partial pressures of 0.095 atm, 0.171 atm, and 0.28 atm for NO, Cl2, and NOCl, respectively. (b) If the vessel has a volume of 5.00 L, calculate Kc at this temperature.
Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: PCl3(π) + Cl2(π) β PCl5(π). A 7.5-L gas vessel is charged with a mixture of PCl3(π) and Cl2(π), which is allowed to equilibrate at 450 K. At equilibrium the partial pressures of the three gases are πPCl3 = 0.124 atm, πCl2 = 0.157 atm, and πPCl5 = 1.30 atm. (a) What is the value of πΎπ at this temperature?
