A mixture of 0.0565 mol phosphorus pentachloride, PCl 5 , and 0.0800 mol helium gas, He, was placed in a 1.000-L flask and heated to 250.0°C. The phosphorus pentachloride decomposes at this temperature to give phosphorus trichloride, PCl 3 , and chlorine gas, Cl 2 . The helium gas is inert. PCl 5 ( g ) ⇌ PCl 3 ( g ) + Cl 2 ( g ) What is the partial pressure of helium in this equilibrium mixture at 250.0°C? At equilibrium, the total pressure is found to be 6.505 atm. What is K c for the dissociation of PCl 5 ?
