An equilibrium mixture of PCl5 (g), PCl3 (g) and Cl2(g) has partial pressures of 217.0Torr, 13.2Torr, and 13.2Torr, respectively. A quantity of Cl2 (g) is injected into the mixture as well as the total pressure jumps to 263.0Torr at the moment of mixing. The system then re-equilibrates.Compute the new partial pressures for PCl3, PCl2 and PCl5?
