# At a certain temperature, an equilibrium mixture

3)Phosphorus pentachloride, PCl5 , is a gas that decomposes according to thereaction: PCl5 (g) PCl(g) + Cl2 (g)3At a certain temperature, an equilibrium mixture was found to contain the followingmolar concentrations: 0. 690 M PCl5 , 0. 910 M PCl3 , and 0. 919 M Cl2. The value of Kcfor this reaction at this temperature is 1. 20. Hint: the specific temperatue is not requiredfor this problem. Determine: (a) how many mol/liter of Cl2 must be removed to increase the equilibriumconcentration of PCl3 by 50% and (b) the final equilibrium concentration of Cl2. _________ mol/L Cl2 removed_________ = [Cl2]eq
