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

Options

A. `(x)/(a)=((K_(P))/(P))^(1//2)`
B. `(x)/(a)=(K_(P))/(K_(P)+p)`
C. `(x)/(a)=((K_(P))/(K_(P)+p))^(1//2)`
D. `(x)/(a)=((K_(P)+p)/(K_(P)))^(1//2)`

Answer

C
