Phosphorus pentachloride, PCI5, an important reagent in organic chemistry for converting alcohols to alkyl chlorides (ROH - --> RCI), is hydrolyzed in water to form phosphoric acid and hydrogen chloride. In the gaseous state, however, PCI5 can decompose at 250C according to the following reaction PCI5(9) PCI3(9) + Cla9), for which K = 0.0240. a) Are products or reactants favored in the decomposition of PCI5(3)? b) If a 5.00-L flask containing 205.5 g PCI5(g) is heated to 250C, what is the equilibrium concentration of each species in this reaction? c) What effect would an increase in pressure have on the equilibrium position? Why? d) If a 2500.-L vessel containing 3250. kg of PCI3(g) with a constant chlorine pressure of 3.525 atm is allowed to reach equilibrium, how many kilograms of PCI5(g) are produced?
