Solid `PCI_(5)` exits as

In solid state, PCI_5 , is a

2 mole of PCI_(5) is heated in a one litre vessel. If PCI_(5) dissociates to the extent of 80%, the equilibrium constant for the dissociation of PCI_(5) is

The reaction, PCI_(5)hArrPCI_(3)+CI_(2) is started in a five litre container by taking one mole of PCI_(5) . If 0.3 mol PCI_(5) is there at equilibrium, concentration of PCI_(3) "and" K_(c) will respectively be:

When formic acid reacts with PCI_(5) it forms

On hydrolysis PCI_(3) gives

Account for the following: PCI_5 behaves as an ionic compound is solid state.

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
