5. Phosphorus pentachloride gas, PCl;(g), will decompose to phosphorous trichloride, PCI,(g), and chlorine, Cl,(g), at 160 °C. In a sealed vessel, the reaction will proceed to equilibrium: PCI, (g) PCI,(g) + Cl,(g) A chemist places 3.00 mol of phosphorous penta- chloride gas into a sealed 1.50 L flask at 160 °C. At equilibrium, he observes there is 0.300 mol of phosphorous trichloride gas and some chlorine gas. Calculate the equilibrium concentrations of gaseous phosphorous pentachloride and chlorine. T/I 5.
