Q.For the reaction $PCl_5(g) \rightleftharpoons PCl_3(g) + Cl_2(g)$ , the degree of dissociation ( $\alpha$ ) at equilibrium is related to total pressure $P$ as:

\alpha \propto P

\alpha \propto 1/P

\alpha \propto 1/\sqrt{P}

\alpha

is independent of

P

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