Gaseous phosphorus pentachloride decomposes according to the reaction PCIs(g) PCl3(g)+Cl2(g) a. The equilibrium system was analyzed at a particular temperature, and the concentrations of the substances present were determined to be [PCIs] =1.1x10-²M, [PC13]=0.325M, and [Cl₂]=3.9x10-3M. Calculate the value of K for the reaction. b. Using your value of K, determine the concentration of [Cl2] present when [PCIs] =5.0× 10-³M and [PC13] -0.225M.
