Question

At temperature T, compound ${\rm{A}}{{\rm{B}}_{2(\;{\rm{g}})}}$ dissociates as ${\rm{A}}{{\rm{B}}_{2(\;{\rm{g}})}}$ ⇌ ${\rm{AB}}({\rm{g}}) + \frac{1}{2}\;{{\rm{B}}_{2(\;{\rm{g}})}}$ having degree of dissociation x (small compared to unity). The correct expression for x in terms of ${{\rm{K}}_{\rm{p}}}$ and p is

Select the correct option:

$\sqrt {{K_p}} $

$\sqrt[4]{{\frac{{2{K_p}}}{p}}}$

$\sqrt[3]{{\frac{{2\;{{\rm{K}}_{\rm{p}}}}}{{\rm{p}}}}}$

$\sqrt[3]{{\frac{{2K_{\rm{p}}^2}}{{\rm{p}}}}}$
