Q.For the dissociation of $PCl_5$ , $PCl_5 \rightleftharpoons PCl_3 + Cl_2$ , if $\alpha$ is the degree of dissociation and $V$ is the volume of the flask, then $K_c$ is:

\alpha^2 / (V(1-\alpha))

\alpha^2 / (1-\alpha)

\alpha / (V(1-\alpha))

\alpha^2 V / (1-\alpha)

The correct solution involves applying the fundamental concept to derive the final value step by step...
