a' moles ofPCl_(5) are heated in a closed container to equilibriate PCl_(5)(g)hArrPCl_(3)(g)+Cl_(2)(g) at pressure of p atm . Ifx moles of PCl_(5) dissociate at equilibrium , then

Answer»

<P>`(X)/(a)=((K_(P))/(P))^(1//2)`
`(x)/(a)=(K_(P))/(K_(P)+p)`
`(x)/(a)=((K_(P))/(K_(P)+p))^(1//2)`
`(x)/(a)=((K_(P)+p)/(K_(P)))^(1//2)`
