At `200^(@)C PCl_(5)` dissociates as follows :
`PCl_(5)(g0hArrPCl_(3)(g)+Cl_(2)(g)`
It was found that the equilibrium vapours are 62 times as heavy as hydreogen .The degree of dissociation of `PCl_(5)` at `200^(@)C` is nearly :

At 200^(@) C PCl_(5) dissociates as follow , PCl_(s(g)) hArr PCl_(3(g)) + Cl_(2(g)) . It was found that the equilibrium vapour. are 62 times as heavy as hydrogen. The degree of dissociation of PCl_(5) at 200^(@) C is nearly.

For the reaction, PCl_(5)(g)to PCl_(3)(g)+Cl_(2)(g)

At 473 K , partially dissociated vapours of PCl_(5) are 62 times as heavy as H_(2) . Calculate the degree of dissociation of PCl_(5) .

At 473 K , partially dissociated vapours of PCl_(5) are 62 times as heavy as H_(2) . Calculate the degree of dissociation of PCl_(5) .

Phosphorus pentachloride dissociates as follows in a closed vesselm PCl_(5)(g)hArr PCl_(3)(g)+Cl_(2)(g) . If total pressure at equilibrium of the reaction mixture is P and degree of dissociation of PCl_(5) is x, the partial pressure of PCl_(3) will be :

For PCl_(5)(g)hArrPCl_(3)(g)+Cl_(2)(g), write the expression of K_(c)
