Relation between K, degree of dissociation and pressure for A(g) = B(g) + 1/2 C(g)

1. A.
   $K = \frac{\alpha^{\frac{1}{2}}p^{\frac{3}{2}}}{\left( 1 + \frac{3}{2}\alpha \right)^{\frac{1}{2}}(1 - \alpha)}$
2. B.
   $K = \frac{\alpha^{\frac{3}{2}}p^{\frac{1}{2}}}{(2 + \alpha)^{\frac{1}{2}}(1 - \alpha)}$
3. C.
   $K = \frac{(\alpha p)^{\frac{3}{2}}}{\left( 1 + \frac{3}{2}\alpha \right)^{\frac{1}{2}}(1 - \alpha)}$
4. D.
   $K = \frac{(\alpha p)^{\frac{3}{2}}}{(1 + \alpha)(1 - \alpha)^{\frac{1}{2}}}$
