PCl_(5) (g) hArr PCl_(3) (g) + Cl_(2) (g) - What effects on equilibrium of the reaction will be observed when (a) chlorine gas and (b) nitrogen gas are added separately at constant pressure and constant volume at equilibrium at a constant temperature ?

2 mol of PCl_5(g) is heated at a given temperature in a closed vessel of volume 2L. As a result, PCl_5(g) dissociates and forms PCl_3(g) and Cl_2(g) . When the dissociation reaction reaches equilibrium, it is found that 50% of PCl_5(g) has dissociated. K_c for the reaction is

2 Cl (g) hArr I_(2) (g) + Cl_(2) (g) , for this reaction K_(c) = 0.14 . If the initial concentration of Icl be 0.78 (M) , then calculate equilibrium concentration of all species in the reaction mixture .

A quantity of PCl_5 was heated in a 10 dm^3 vessel at 250^@C . PCl_5(g) iff PCl_3(g) + Cl_2(g) At equilibrium the vessel contains 0.1 mole of PCl_5 and 0.2 mole of Cl_2 The equilibrium constant of the reaction is

The equilibrium established during thermal dissociation of PCl_(5)(g) in a closed vessel is as follows: PCl_(5)(g)hArr PCl_(3)(g)+Cl_(2)(g) If the degree of dissociation of PCl_(5)(g) at equilibrium be 'x', then show that (1) 'x' is inversely proportional to the square root of the total pressure of reaction mixture at equilibrium and (2) 'x' increases with increase in volume of the system.
