Consider the following gas phase dissociation, $\mathrm{PCl}_5(\mathrm{~g}) \rightleftharpoons \mathrm{PCl}_3(\mathrm{~g})+\mathrm{Cl}_2(\mathrm{~g})$ with equilibrium constant $K_P$ at a particular temperature and at pressure $P$. The degree of dissociation ( $\alpha$ ) for $\mathrm{PCl}_5(\mathrm{~g})$ is

$\alpha=\left(\frac{\mathrm{K}_{\mathrm{P}}}{\mathrm{K}_{\mathrm{P}}+\mathrm{P}}\right)^{1 / 3}$

$\boldsymbol{\alpha}=\left(\frac{\mathrm{K}_{\mathrm{P}}}{\mathrm{K}_{\mathrm{P}}+\mathrm{P}}\right)$

$\alpha=\left(\frac{\mathrm{K}_{\mathrm{P}}}{\mathrm{K}_{\mathrm{P}}+\mathrm{P}}\right)^{1 / 2}$

$\alpha=\left(\frac{\mathrm{K}_{\mathrm{P}}}{\mathrm{K}_{\mathrm{P}}+\mathrm{P}}\right)^2$
