1.	PCl_(5)(g) hArr PCl_(3)(g)+Cl_(2)(g) 'alpha' is the degree of dissociation of PCl_(5) at equilibrium pressure 'P'. Which among the following is the correct expression for degree of dissociation of 'alpha' ?
Answer» <P>`ALPHA = SQRT((K_(p))/(P+K_(p)))` `alpha = sqrt((P+K_(p))/(K_(p)))` `alpha=sqrt(K_(p)P)` `alpha = sqrt(P//K_(p))` ANSWER :A
