3 gram-molecular phosphorus penta-chloride was heated in a vessel of volume 4 litres. Equilibrium...

When a gas is heated in a vessel of constant volume , the pressure increases because

3 g mol of phosphorus is heated in a flask of 4 L volume. At equilibrium, it dissociates to give 40% of phosphorus trichloride and chlorine. Calculate the equilibrium constant.

2 g molecule of PCl_5 are heated in a closed vessel of two litre capacity. When the equilibrium is attained , PCl_5 is 40% dissociated into PCl_3 and Cl_2 . The equilibrium constant is

3 mole of PCl_(5) were heated in a vessel of three litre capacity. At equilibrium 40% of PCl_(5) was found to be dissociated. What will be the equilibrium constant for disscoiation of PCl_(5) ?

2 moles of PCI_(5) was heated in a closed vessel of 2 litre capacity. At equilibrium, 40% of PCI_(5) is dissociated it PCI_(3) and CI_(2) . The value of equilibrium constant is
