Chemistry

An equilibrium mixture of PCl5(g), PCl3(g), and Cl2(g) haspartial pressures of 217.0 Torr, 13.2 Torr, and 13.2 Torr,respectively. A quantity of Cl2(g) is injected into the mixture,and the total pressure jumps to 263.0 Torr (at the moment ofmixing). The system then re-equilibrates. The appropriate chemicalequation is

PCl3(g) + Cl2(g) <---> PCl5(g)

Calculate the new partial pressures after equilibrium isreestablished.

P PCl3 = ? torr

P PCl2 = ? torr

P PCl5 = ? torr
