For a reaction at equilibrium
`A(g)hArr = B(g) + 1/2 C(g)`
the relation between dissociation constant (K), degree of dissociation `(alpha)` and equilibrium pressure (p) is given by :

A

`K=(alpha^(1/2)p^(1/2))/((1+3/2alpha)^(1/2)(1-alpha))`

B

`K=(alpha^(1/2)p^(1/2))/((2+alpha)^(1/2)(1-alpha))`

C

`K=((alphap)^(3/2))/((1+3/2alpha)^(1/2)(1-alpha))`

D

`K=((alphap)^(3/2))/((1+alpha)(1-alpha)^(1/2))`
